Description

Kind name

Mysterious

The field of technology relates to two sets of devices connected in series between an AC power source and a lighting device.

Since then, lighting installations using contact switches such as triac irristors have been put into practical use. From the ground of these wires, two wires are common and are connected in series between the AC power source and the load. Thus, in a load device connected in series between an AC power supply and a load, the problem is how to secure its own source.

Three

5 is connected in series with the AC power supply load 3, 5 and control 5, 5 for supplying stable power to the control, and 5 power when in the load 3 state. When the load 3 is supplied, 5 is supplied when the load 3 is supplied 3 56, and the current of the load current is composed of the row 57. Switch 5a of 5 is composed of a triac. In the off state of the load 5 that is not supplied with power, the voltage applied to the load from the AC power supply 2 is supplied to 55 via 5.

55 is a path composed of a resistance diode. At this time, the current flowing through the load 3 is a current that the load 3 does not produce, and the impedance of the small 55 of the control 53 is set to be maintained.

Five

On the other hand, in the ON state of load 5 where load power is being supplied, 3 5 is increased by the signal from control 53, and the impedance of load 5 is reduced and the amount of current flowing to load 3 is increased. The flowing current is

5 also flows, and the buff capacitor 5 starts to be charged. When the electric voltage of the buffer capacitor 5a becomes higher than a predetermined value, the diode constituting the 3 5 breaks down and current starts to flow, current flows into the gate of the auxiliary 57, and the auxiliary 7 is activated (). As a result, 52 to 3 5 The additional current flows into the gate of auxiliary 57 and 5 switches a (5). Therefore, almost all power is supplied to the load. () Continues to pass current, but when the alternating current reaches the cross point, switch 5a is self-

(State). When 5 (state) is reached, the current flows through 5 to 3 5 again to 5th, and the source of load 5 is secured. In other words, every two phases of exchange, the load

Securing the source of resources, passing through assistance 7 and the work of main 5 are repeated. 5 shows the AC power supply load 3 connected in series 6, 6, control 3, 6 for supplying stable power to the control city 63, and load 3 It consists of 2 6 to supply 6 power sometimes, 3 6 to supply 6 power when the load 3 is being supplied, and a cross 7 to detect the cross point of the load current. 6 Switch 6a uses MOS and controls incandescence.

7

When power is supplied to 3, the switch 6a of 6 is turned on only for a period according to the externally applied level, but the switch 6a is turned on when the zero cross 67 detects the voltage crossing point () Over time, the main switch a is set to (state). In 6 (state), the source of load 6 is secured as above. When set to 6 (state), the cross 67 again detects the cross point and repeats the operation of setting the switch 6a to () every two AC periods.

8

However, in any of 5 above, 55 is provided to operate the control 53 in the state of load 3.

It is necessary to continue supplying power to 5. For this reason, the current continues to flow through the load 3 even though it is very small, and the load 3 that can be connected is limited. When the 5 switch is a triac irristor, the noise generated when power is supplied to the load 3 is reduced to prevent the operation caused by the noise propagated from the power supply when the supply of 3 is stopped. Therefore, it is necessary to provide a fill. However, the size of the coil 5 constituting the fill and heat generation due to the coil become problems, and it is difficult to mold the load device.

1 In order to reduce the noise due to the load without using the fill, the load (3) described in the example has a switch part that is more on than this switch (switch) in addition to the switch element. The switch part that has been lowered is made to move. However, in such a case 3, the number of switch elements increases, the circuit configuration becomes complicated, and the switch-on timing becomes complicated. In recent years, light has become popular due to the demand for energy.

When 6 switch 1a is a transistor as in 6, the load is limited to a load in which the load current and load voltage are in phase () due to heat. For this reason, there are demands for two sets of devices that select the type of load to be connected, such as fluorescent lamps and incandescent lamps. In addition, a triac transistor, which is used as a switch element, is generally composed of s and a current flows in the direction of the element. In the case of a triac, since there is a junction in the current path, a loss occurs due to the current passing over this wall. In addition, in the case of a transistor, it is necessary to connect the two elements in the opposite direction, and the resistance of the carrier serving as the holding layer is high, so a loss occurs in energization. As a result, the heat generated by the switch itself is large, and a large heat sink is required, resulting in an increase in the size and size of the load device. Generally, this load is used by being stored in a metal box or the like provided on the wall surface. However, since there is a limit to downsizing in the conventional installation, the box that is currently used generally is used. If it is too long, it cannot be used with other sensors or loads. Therefore, in order to make it possible to install a load and other sensor switches in a general size, further downsizing of the load device is required.

Mysterious

The problem to be solved is to solve the above problem, and it is possible to reduce the amount of heat generated in the load, to reduce the size and increase the volume. The purpose is to provide a load station that does not require a load limit.

1 4 Another object of the present invention is to provide a load device capable of accurately controlling the switching timing while reducing the number of switch elements.

1 5

The other purpose of Ming is to abolish the configuration corresponding to 2 above, The purpose is to provide a load device that can prevent a minute flow from flowing. On the light side, there are two sets of devices connected in series between the AC power supply and the load. A switch with a de-algate transistor to control the supply of power to the load

A switch having a thyristor structure, and when the switch is not connected, an auxiliary unit that controls supply of power to a load; a control unit that controls the unit; and a power supply that is supplied from the end, Supplying a stable voltage, being supplied with power from the end, and supplying the load when the supply of the load is stopped 2, a path for driving the unit, and And a voltage for detecting a voltage input to 3 and 3 for supplying the source of the part when supplying a load, and when the load power is supplied, When it is detected that the voltage input to 3 has reached a predetermined value, is set to a fixed time, and when is not, the is set to a second fixed time.

7

According to the obvious aspect, the structure of the two switch elements is a dual gate transistor structure that is an efficient semiconductor chip structure for () conversion in AC control. Can be realized. It has a transistor-type switch, which controls the supply of power to the load, and has a thyristor-type switch, and controls the supply of power to the load when the above is not Power is supplied from the end of the auxiliary and the control capital to be controlled by the unit, and a stable voltage is supplied to the base, and the power is supplied from the end to stop the supply of the load. Supplying the source of the part 2, and supplying the source of the part 3 when supplying the load when the is closed and supplying the load. A voltage to be detected and a cross to detect a cross point of the load current, and when the load power is supplied, is counted from when the voltage input to 3 reaches a predetermined value. And the zero cross is Only time that the inter-3 scheduled periodic full load current counted from the detection of the cross point of the load current is Ru overlap, the It is characterized by guiding. According to the clear aspect, when the voltage detected by the third person reaches the predetermined value, the control is turned on for a fixed period of time. Power is supplied from the main part to the load. In addition, even if within this fixed time, if 3 fixed time elapses, the control is turned off (set to the state). The Lord is surely dismissed before becoming. This ensures that is not crossed over the load current.

2

It has a transistor switch on the three sides, and controls the power supply to the load.It has a thyristor switch and controls the power supply to the load when the above is not An auxiliary power supply, a control capital controlled by the unit, and a power supply from the end to supply a stable voltage to the capital.

When the above is closed and supplying a load, a receiving unit that receives a control signal transmitted from three units that supply the source of the unit, and a control signal received by the receiving unit are rectified. And an independent power source for supplying power to the load.

twenty one

According to the third aspect, since the independent power supply rectifies the control signal received by the receiving unit and supplies power to the power supply, the conventional configuration corresponding to can be eliminated. In addition, since this stand-up power supply supplies power independently of the load, it is possible to prevent a minute current from flowing through the load and to expand the range of connectable loads.

Good for carrying out Ming

(Ming)

First, the switch used in the load device described below will be described. (a) shows the path diagram of the switch element of the Lugate transistor, and (b) shows the path diagram when two M s F transistor elements are connected in reverse. Or, a cross-sectional configuration of a switch element made of a dealgate transistor is shown.

Three

In the configuration shown in (), the source s of one transistor is connected, Since it is grounded () and does not require withstand voltage between the source S gate GG and withstand voltage between the gate GG and drain DD, it requires two (for example, opening a gap). Since it operates with a gate signal based on two transistor source poles, it can be driven by inputting the same signal to the gate G2 of the transistor element. On the other hand, as shown in Fig. 1, the Lugate transistor switch has a structure that realizes a loss-free direction with one place where the pressure is maintained. On the other hand, it is necessary to control the pressure of the drain D D2 formed in this way as a reference, and it is necessary to manually drive the drive signals for the two gates G (hence, this is called the “Lugard transistor structure”).

2

3 is a route diagram showing the formation of the load according to the clear state, and is a time chart showing the signal in the load section. Here, the physical structure of driving is not shown, and the physical structure of driving will be described below.

Five

1 in state II shown in Fig. 3 is connected in series with the AC power supply load 3, and controls the supply of power to the load 1, 1 driving 12, and 12, the control capital controlling the load body 1 to supply stable power to control 13, 2 to supply power 1 when load 3 is applied, and 3 to supply power when load 3 is supplied The current of the load current is composed of row 17 and the like. Further, the voltage 6 for detecting the voltage input to the voltage 3 is further provided in the voltage 36. 1 has a switch a made of the above-described dual gate transistor, and the auxiliary 17 has a switch made of a thyristor.

6 Even when the load that is not supplied with 3 is off, a current flows from the power supply to 2 15 via 12 through the power supply, so a small current flows through load 3, but the load 3 is not created. To a low level

The impedance of 1 is held at a high value.

7

3 When power is supplied, the impedance of 3 is lowered, current is passed through the load section, and 1 buff capacitor 5 is charged. As described above, voltage () 8 is provided in 3, and 6 is detected as a human-powered voltage. When 8 detects that the voltage that is manpowered to 3 has reached a predetermined value, voltage 8 Output the number. Upon receiving a signal from the voltage, the capital 13 outputs a pulse () for causing the drive to go to 1 so as to keep (set) for a fixed time. In the case of 3, the pulse (1) is output directly according to the signal from voltage 1, so that the pulse (

) A configuration in which 9 is provided as part of control 3 is shown. Or, it is not limited to the above configuration, and it may be configured such that the force from the voltage is input to the main control configured by, and the second pulse signal is output by software.

It is preferable to set the fixed time for the time slightly shorter than the period of the wave number source.

8

Next, when the main time starts the operation to become the (state) after the fixed time has elapsed, the control 3 causes the auxiliary 1 to be in the state (for example, several hundreds) only for a predetermined time. This becomes, and the load current is constant.

When it starts to flow to 7, the flow continues to auxiliary 7 until the load current becomes zero. In 3, 2 pulses that output 2 pulses () for 2 fixed times are set as part of control 1 so that the drive signal is given to 1 7 only for a fixed time after detecting that has entered (state). An example is shown. Alternatively, the second pulse signal may be output by software, or the same operation may be realized by a delay circuit using a diode capacitor.

2

Referring to Fig. 4, after these operations, after the buffer capacitor 5 is completed, the main current is supplied from the main to the load 3 for the most part of the period of the commercial power source. The power is supplied to the load 3 from the power source. Since the auxiliary has a thyristor switch 7a, it becomes (state) at the point of time (zero cross) when it becomes current. 1 When 7 becomes (state), current flows into 3, so the above operation is repeated for each cycle of the source. Because it is done for these load currents,

Even if it is constituted by a switch 1a having a transistor structure, the load 3 is not limited to a power factor, and can realize a formula that is suitable for a fluorescent lamp and a deviation thereof. In addition, in this implementation, since it is configured with a switch a made of a dual gate transistor, it is limited to the place where the pressure of the transistor element is necessary, and the heat quantity of the switch element itself at the load is reduced, so that Molding and mass production can be realized at the same time.

Three

In addition, 3 is provided with 22 to detect the current flowing through auxiliary 7 As an example, this is done by switching the load current path from auxiliary 7 again when frequency is shifted or connected.

This is to protect 7 from destruction.・ 22 is not always necessary, it should be provided if necessary. (

Next, I will explain about 1 used in load A according to the clear state with reference to 56. 5 is the road map for load A, and 6 is for 5. As shown in Fig. 6, the drive for is made up of a conductor switch 1 such as a photocoupler that corresponds to the gate of switch a. Conductor switch

Each of the a's is a number from Goto 3. When a drive signal is input, the conductor switch a 2 converts the force into light energy and outputs it. Conductor switch

When the light from light emission a, 2 radiates to 1 b of 1 2, photoelectric conversion is performed at b, and energy is converted into electrical energy (ie). 2 is based on the point where the generated power is connected to the AC power supply (), respectively)

Switch 1 of 1 is connected so that a positive potential is applied to the gate part of a 33

By outputting a drive signal from 3 and emitting a in conductor switch 1 1 2, the gate drive signal of 1 switch 1 a, which is the reference position, can be easily manpowered. can do. Note that a and 21 b of conductor switch 2 are electrically insulated, so they are not driven into the gate of switch 1 unless light is emitted from light emission 1 a 2. In other words, the gate of the switch a is supplied with electric power that is electrically isolated from the control 3 (which is 1 of the load A) different from the drive signal output from the control 3. Also, based on the signal from the control city 13, the conductor switch 2 connected to the gate of the main switch 1a can be easily turned on / off while maintaining the insulation.

Three

7 indicates that shown in 5-6. In this For conductor switches such as photo

a are connected in series. As a result, the current flowing to the drive can be reduced to about 2, and the power consumption during the drive can be reduced.

35

(2)

Next, it will be explained with reference to 9 for use in the load A according to the obvious state. Is the route map of load A related to the condition, and 6 is 1 in 5.

Three

As shown in Fig. 9, 1 for driving 1 is provided corresponding to the gate of the switch, diodes 1a and b connected to 1 1 of load A, and one end to each power line. It consists of capacitors 2 and 1 connected to diodes a and b, and a drive switch 33 connected between the diode O b continuum and the gate element of the main switch a. Switch 3 is controlled by a signal from control 13. In addition, this switch

3b is a configuration in which the switch section is insulated. Switch

The composition of 3 is not particularly limited, and types can be used as described below.

37

According to this construction, a simple source based on the potential of the power line is formed by this capacitor 2 by connecting the load A via diodes a and b to one end connected to the power line. The The current flowing through the power line on the low voltage side from the power supply voltage side of the capacitor 2 through the A power supply charges the capacitor connected to the voltage side. Is called. At that time, since the capacitor connected to the voltage side is not charged, the charging is repeated in the cycle of the power supply frequency. The capacitor is charged at the opposite timing of the potential relationship of the power line.

8

When a dual gate transistor switch is used, the voltage must be applied to the gate of the main switch 1a with reference to (1) where the power line is connected. Here, according to the issue from Control 13

When the switch connected to the gate of switch a or 3 is connected, the gate element of switch 1a Switch 1a becomes () because the voltage charged in the capacitor is marked. When switch a is in the state, the pressure of switch a becomes very small, so that it is possible to maintain the voltage generated from the source of load A via the diode b switch.

Three

In this case, since the drive is configured with 14 edges, it is possible to supply drive power at a rate. Capacitor 2 2 can temporarily determine the position of the gate pole when switch 1 becomes, so it can be in that shape or a small one. Note that in 9 the drive power is supplied from the power of 1, but the power may be supplied from a relatively stable power supply such as the power of 1. Shows the physical nature of the implementation and uses a conductor switch such as a photo-photorelay as the drive switch. When a signal from 3 is input, an optical signal is output from the conductor switch element, and when the signal shoots into the receiver,

() From. As long as light is output from the light emitting part, the gate of the switch 1a is not driven by human power. Therefore, based on the signal from the control, the drive switch connected to the gate of the main switch 1a can be easily turned on and off while maintaining the insulation.

Four

Indicates the 1 shown in. In this case, a drive switch using a conductor switch such as a photocoupler or photorelay is connected in series. As a result, the current flowing to the drive can be reduced to about 2, and the power consumption during the drive can be reduced.

Four

Indicates other variations of 1 1. In this case, the drive switch a 3 using a conductor switch such as a photocoupler or photorelay is connected in series.

Capacitor between the gate drive switch 3 of the switch a and the power line connected to the gate electrode of the switch a

Is connected. Note that capacitor a b may be added as shown in.

0 Three

As shown in this figure, by adding content, when the drive switch 3 3 is turned on and off, the capacitor

By b, the drastic change in the gate voltage of switch a can be mitigated. ・ Switch 1a can be prevented from turning on and off sharply. As a result, noise generated by turning on / off the main switch a can be reduced, so that the noise fill can be reduced or omitted. That is, compared to the configuration shown in 44 or FIG. 5, a coil capacitor that functions as a noise fill can be obtained. With regard to the coil constituting the noise fill, the coil becomes larger as the load flow becomes larger. Therefore, if the coil can be made, it is possible to realize the device type. In addition, regarding the contin that constitutes the noise fill, there are fewer restrictions on the load placement compared to the coil, but the presence of this capacitor reduces the impedance of the load when the load is in the state. Connected, not preferred for off-loading. Also, even when the load is in the off state, a current flows through the capacitor, which may cause a load to be created when the load is off. Therefore, if a noise filter capacitor can be formed from the load device, this is the preferred form for the second device.

45

(3)

Next, we will explain the load related to clear state 3 with reference to 178. 17 is the load diagram for 3, and is for 7.

6

Then, 1 is composed of transformers () 3 and 4a b that transmit power by electromagnetic coupling, such as high-frequency transformers, and oscillation circuits. The coil 1 a of the transformer 3 is connected to the oscillation circuit 5, and the oscillation circuit 15 is further connected to the control 13. When a signal from control 1 is input to the oscillation circuit, the oscillation circuit 15 oscillates and generates AC power only while the drive signal is marked. When an alternating current generated by the oscillation circuit 15 flows in the coil 3 of the transformer 3, an electromotive force is generated in the coil 3 due to electromagnetic conduction. Since the power generated in the two coils 3 b 3 of the transformer is alternating current, it is fed by, 4 and then input to the gate of the switch a of the main control. In addition, based on the source and the point to be connected, The gate of switch a is connected so that a positive potential is marked. Note that the coil 3 and the coil b 1 3 of the transformer 1 3 are isolated from each other by electricity, so that as long as current does not flow through the coil 3 of the transformer 1, no drive input is made to the gate of the switch 1a. Ie

The gate a is supplied with electrically isolated power from control 1 that is different from the drive signal output from 1.

7

In this way, AC power is generated by the oscillation circuit 5 using the signal output from 3 as follows, so the wave number and width in the oscillation circuit 15, the number of coils 3 and 3 3 of the transformer 3, etc. As a result, the desired power can be generated in the coils 3 of the transformer 3. Therefore, even if the gate part of the switch 1 of 1 is a switch element of a current that requires a certain amount of electricity, it can be driven stably. Needless to say, the dynamic power of the oscillation circuit 15 is supplied from any part of the load device. Alternatively, the oscillation circuit 5 may be configured to directly output a pulse signal having a predetermined wave number and width from the control.

48

( Four )

Next, we will clarify the load related to the clear state with reference to 9. In the load device according to (1), when a drive signal is applied to the switch (a), the circuit configuration is such that current does not flow due to the diode (1). Only come. In this case, even if one switch a is a current switch that requires constant power, it can be driven stably. As shown in the figure, in the load related to, the synchronous switch 1 1 is connected between the negative output that becomes the line circuit level of 2, and the synchronous switch is synchronized with the operation of

Perform the action that becomes. When this switch 2 is taken in synchronization with the operation of, a path is formed to flow current from the load to the gate of switch a. Therefore, even if the switch gate portion is a dual gate element that requires current, it can be driven stably. The configuration is the same as that of the other configurations and the above-described implementation, and the configuration of the drive 1 is not particularly limited. You can.

(

Next, with regard to load C according to clear state 5,

Clarify with reference. Is a path diagram showing the composition of load C according to 5, and is a time chart showing signals in the load C section. The load C according to 5 further has a voltage zero cross (with zero output) 23 Vals () 2 provided in 3 1, which is in a state of supplying power to the load, as shown in 3. The physical configuration of the drive 1 may be any of those exemplified in .about.3. When zero cross 23 detects a voltage zero cross, 3 pulses output 3 constant time pulses (). 2 As shown, the 3 fixed times of 3 pulses correspond to the time slightly shorter than the period of the power supply period.

The drive signal is input to the gate of the switch a so that only during a period in which both one pulse () and three pulses () are applied.

52

In the equation, when the connected load is small, the time required for the capacitor 5 to be charged increases. In this case, in the operation shown in the figure, the main action is performed after the end of charging, and the signal may be extended until the current exceeds the current zero cross point. If the main is opened and the auxiliary 7 is closed in this state, the load current, which is the current, is energized by the auxiliary 7, and the operation with the voltage supplied in the cycle of the commercial source described above is lost.

53

However, as shown in Fig. 5, it is possible to control so that is not driven over the period of the commercial source based on the voltage zero-cross signal by combining the voltage zero-cross signal, regardless of the amount of load connected to the load C. The operation of securing the power supply can be stably realized at every commercial source cycle.

(6)

Next, the load D according to 6 of the clear state will be explained with reference to 2. Is a path diagram showing the construction of load D according to 6, 3 is 1 in, and is a time chart showing the signal in the portion of load D. Three 55

In the load D according to 6, the voltage is connected to the diodes a and Ob of the voltage connected to the load D, and the capacitors 2 and 2 are connected to the respective power lines and connected to the diodes a and b, respectively. Diode b Switch of photo thyristor or photo triac connected between capacitor a and main 1 switch a gate

It consists of 5a 5.

Five

3 Depart at voltage 8 provided in 1 and

Move on to. At that time, a signal is input to drive the drive switches 5 and 5 connected to the gate of the switch a. However, since these drive switches 5 5 are made of an irristor or triac, only the drive switch number is required. Therefore, the driving power of the drive switch 55 can be made smaller than that in the above state. In order to set the drive switch 55 to, it is possible to reduce the dynamic electric power for opening and closing the switch simply by opening the synchronous switch 22 provided at. For a device, the important issue is how to ensure stable power supply while enabling load control, so the low power consumption of the load device is important for the operation of the load.

57

(2)

The load device according to the clear state will be described. Is a path diagram showing the composition of the load related to the state, and 2 8 is the load

It is a time teat that shows the signal in each part.

Five

1 in the state shown in 25 is connected in series with the AC power supply load 3, and when the power supply to the load 3 is controlled, 12, the control city 13 that controls one load, and the control 3 1 to supply stable power to the power source, 4 to supply power when the load is 3 2 2 to supply power when 3 is supplied, and 3 It consists of lines 17 and so on. Further, 3 1 is provided with a voltage 8 for detecting the voltage input to 3 and a low loss 23 for detecting a cross point of the load current.

Has a transistor switch a, and the auxiliary 17 has a thyristor switch 17a. Also, for control 3, use PU, etc. 4 The main control capital formed, 1 pulse, 3 pulses 2 and pulse 2 are provided.

Five

Pulse 1 outputs a pulse only for a fixed time after receiving the buff capacitor signal from voltage 18. That is, the pulse rises in response to the signal from voltage 18 and falls after a fixed time. After 3 pulses, zero cross 2 detects the load current cross point, 3 pulses are output to limit the state of main 1 at a fixed time. In other words, 3 pulses rise from the zero cross 23 in response to the cross signal, and fall after 3 fixed hours. 2Pulse 2 outputs a 2-pulse signal for a predetermined time so that it is set to 1 only for a fixed time after it is detected that is in (state). In other words, the pulse of 3 rises when it detects that it has entered the state (and goes down for a fixed period of time 2. Even when the load of 3 is not supplied, the load goes to 15 via 1 from the power supply. Since a current flows, a very small current flows through load 3, but it is kept low enough not to create load 3.

The impedance is held high. 3 When power is being supplied 3 Lower the impedance of 1 and pass current through the load to charge the 4 buff capacitor. As described above, 3 1 is provided with a voltage () 8 and 3 detects a voltage that is manpowered. 18 is 3

When it is detected that the voltage input to 6 reaches a predetermined value, the voltage 18 outputs a predetermined signal to the control city 1. When 1 3 receives a signal from voltage 18, it is set to 1 for a fixed time. 1 is configured to provide pulse 1 that is configured in software using a dedicated C as a part of control 13 so that the first pulse signal is output directly according to the signal from voltage 18 It shows. Alternatively, the present invention is not limited to the above configuration, and the configuration may be such that the force from voltage 18 is input to the main control configured by, and the second pulse signal is output in software. It is preferable to set the fixed time to a little longer than the period of the commercial wave source.

6

Next, when starting the operation to become the main 1 (state) after the above-mentioned fixed time has elapsed, the control city causes the auxiliary 17 to move for a fixed time (for example, several hundreds). (Let's make a state) If this Auxiliary 17 is a little later than (state). Alternatively, the control pulse 2 may output a pulse signal to the auxiliary 7 that is longer than the pulse output from the control city 2 by a fixed time. Alternatively, the extension circuit may be configured using a diode capacitor. By these operations, after the buffer capacitor is completed, power is supplied from the main to the load 3 for most of the period of the commercial source, and then the power is supplied from the auxiliary 17 to the load 3 after the energizing current decreases. Will do. Since the auxiliary 7 has a thyristor switch 17a, it becomes (state) at the point of time (zero cross) when it becomes a current. When 7 becomes (state), current flows again into 3 16, so the above operation is repeated for each source cycle. Indicates the signal at the part of the, and 278 indicates the signal at each part of the. Note that 27 represents a case where 1 control is performed using only the above pulses, and 8 represents a case where is controlled using 3 pulses.

Five

In other words, when the load 3 to be continued is a quantity, as shown in 2, the buffer capacitor 2 is charged in a short time, and after that, the load is mainly loaded during the most part of the cycle of the commercial source. 3 will be supplied with power. At this time, since the fixed time is set so that the main is taken before the current point (zero crossing), the crossing over the zero crossing point will not be in the state. However, when the load 3 to be connected is a quantity, the load current is small, so a lot of time is required for electricity. Therefore, as shown in 7, the time from when the zero cross detects the cross until the end of charging is detected at the voltage 18 becomes longer, and the rise of the pulse is delayed. The fixed time is set according to the above, so if the rise of the pulse is delayed too much, the first pulse falls after the load current exceeds the cross point. Therefore, when controlling using only the pulse, the crossing point is set to 1 state, and the electric operation for each half cycle is not stable.

7

Therefore, in this embodiment, 3 pulses output from 3 pulses are used to limit the main state in 3 fixed times. 3 pulses 6 , Zero cross 3 rises upon detection of cross and falls to for a fixed time. These three constant times are set shorter than the load current cycle.

68

Pulses output from pulse 1 and pulses output from pulse 3 are input to the control. 13 has AND 5 and takes pulse 3 and outputs it to 1. As a result, is closed only for the fixed time when the pulse rises and the 3 fixed time when the third pulse rises. As described above, the pulse rises when the zero cross 2 detects the crossing point, and falls in the third fixed period shorter than the load current cycle. Even if the timing at which the fixed time starts is shifted later, the power wave number crossing point will not be exceeded. As a result, half-cycle charging can be performed reliably and operation can be determined. Even if the load a is composed of a switch a having a transistor structure for the load current, the load 3 is not limited to one having a power factor, and an expression suitable for both fluorescent lamps and It can be realized, and by using a gate switch of a rugged transistor configuration, it is possible to simultaneously realize a large load capacity.

6

According to the load 1 related to the state 2, when the voltage input to the voltage 3 1 is detected to reach a predetermined value, the control 3 causes the signal to enter the state for a certain period of time. After that, most of the time, power is supplied from the main to the load. In addition, even if within this fixed time, if 3 fixed time has passed, the control city 13 will be set to (because it will be in a state, for example, even if the timing at which the fixed time is started is delayed, Mainly taken before the load current becomes.

Is not exceeded beyond the load current level, charging can be reliably performed during the period of the AC power supply.

7

In addition, when the main time becomes lapsed after the fixed time has elapsed, auxiliary 1 is allowed to operate for three fixed hours, so that the energizing current decreases after supplying power from the main unit to the load during the period of the commercial source. After that, power will be supplied from the auxiliary 7 to the load. Since this is performed for these load currents, even if 1 1 is composed of a switch a having a transistor structure, the load is not limited to one with a power factor of 1, and an expression suitable for a fluorescent lamp and a deviation is also provided. Realizing 7 You can. In addition, since the level of noise generated in the device is kept low, it is possible to realize a load device that is small and has no enclosure.

7

(3)

The load devices according to the three states will be explained. Fig. 5 is a route diagram showing the composition of the load related to the state. "Auxiliary

The load according to the embodiment is different in that it further includes an OR 25 for detecting the current flowing in the circuit and operating in accordance with the signal output from the circuit 22, and others are the same. OR 5 is provided at stage A 5 a of control 13.

7

17 is originally intended to detect the crossing point of current, and is not intended for energization, and is expected to be composed of small switch elements. However, if the wave number shifts in a commercial source, or if the load unit is operated for 5 H and 6 Hz, the time between the disappearance of the current and the crossing of the current becomes longer. The energization was started before the load current became sufficiently small. In addition, when connected as a load, even if it is the same with the auxiliary, there is a possibility that the switch element composing the energization will be damaged. Therefore, in state 3, when the current flowing to 7 is detected by current 22 and a current exceeding the current that can be assisted is allowed to flow, only the time (4 fixed time) is allowed again.

When A becomes (state), let Auxiliary 7 go again.

73

More specifically, the current 22 detected that the current exceeding the current allowable by the auxiliary 17 flows and outputs a signal to that effect to the control R 5. When OR 2 receives the force of any of the signals from current 2 from A 5 described above, it protects Auxiliary 7 by shortening for a short time. By repeatedly switching the auxiliary 7 in this way, the loss of the auxiliary 7 switch is prevented, and the compatibility with commercial sources and the load is improved.

7

According to the load related to state 3, when it is detected that the current 22 exceeds the current in the auxiliary 17, the state is changed to (the state), and the state is set. This prevents loss of the auxiliary 17 switch element, and the auxiliary 17 can be configured with a small switch element, making it possible to mold the load device, and adapting to commercial sources and handling loads. 8 .

75

In addition, the control 3 is not limited to the above state, but at least the control 3 is a pulse that receives and outputs the signal of the buff capacitor 2 from the voltage 8, and the pulse that receives and outputs the cross point of the load current from the zero cross It should be configured to control the work based on it. In addition, for example, 3 pulses are configured so that the force from the zero cross 23 is input to the main control 2 configured by C and the like, and the second pulse signal is output in software. Anyway.

()

Next, with respect to the load G related to the clear state, it is possible to adopt the above-described state of G and the deviation thereof, which are described with reference to 3.

77

The load G related to the four states is used to control a plurality of light fixtures, for example, in a home such as a commercial building of an office building. For example, a plurality of loads G are distributed on a control panel installed in a remote location. The control is configured to control the on / off of the load G in response to a motor control 27 from a switch (not installed) or the like installed at a remote location. For this reason, a switch is connected to the main control city 2 via wiring, and when the self control superimposed on the moat control 27 is recognized by the main control, the control signal is output from the main control.

78

3 shows the composition of load G related to the condition. In this case, the main control 2 is further connected with a rectification path 2 and the power from the motor control 7 is rectified to secure the main control city 2 (or control city 13 source). In this way, even if the load is in the state, 15 is provided to secure the source of main control, so that a weak current flows through 3. However, in this way, the main control city 2 By securing a separate source of power, 2 15 is no longer needed, thereby increasing the load

In the state of G, the load 3 does not have enough current, and the load 3 can be prevented from being turned on or off.

( Five )

The following describes the load device according to the following five states. 32 is Ming 9 It shows a load system using the load device according to the state. The system 3 is composed of a plurality of units and a parent control 3 for remotely controlling them. The number of loads 1 connected to the control city can be determined.

The parent control 3 is continued by wire, but may be continued by radio. 1 receives the control signal transmitted from the parent control 31, and controls the load 3 connected to each of the control signals according to the signal. A control signal is transmitted to the control in control city 3. The control signal transmitted from control 1 is accompanied by a dress number corresponding to one of them.

When the control signal transmitted with the dress number assigned to itself is received, it operates according to the signal and controls the load 3. In 32, the load connected to the parent control 3 is not limited to the load H related to, but may be the load 1 related to the load 1 1 5 related to 2 described later. Alternatively, a configuration in which these H's are combined and connected to the control city 3 may be employed.

8

()

33 is the load related to the load used in state 1.

A path diagram showing the composition of H, and 3 is a time chart showing the signal in the load H section. H shown in Fig. 3 is connected in series with the AC power supply load 3, and controls the supply of power to the load 3, 1 and the control capital that controls the load H body and the control capital is stable. 1 when supplying power and when load 3 is supplied

1 When supplying power 3 and load 3

1 An independent power supply that supplies power, a receiving unit 1 a that receives a control signal transmitted from the parent control 31, and a line 7 that supplies the current of the load current. In addition, 3 6 is further provided with a voltage 1 for detecting a voltage manually applied to 3 1. Has a transistor switch a, and the auxiliary 17 has a thyristor switch a. From the control city 31, a (pulse) for remote control of any H is always issued. The H receiver 16a receives this signal and transmits it to the main control city 2. The control received by the transmitter 6a is also transmitted to the independent power source 2. The vertical power supply 2 rectifies the pulse current that forms the control signal,

1 (ie main control) Supply power. Regardless of the operation of the load 3, it is always output from the control 3, so that the power is supplied to the independent power source 26-1 even when the load 3 power supply is not performed. That is, vertical power supply Load 3 supplies power to 1 independently of AC power supply 2 connected in series.

82

On the other hand, when power is supplied to load 3, the impedance of 3 1 is lowered, current is passed through load H, and 1 buff capacitor 2 is charged. As described above, the voltage () is provided in 36, and the voltage input to 36 is detected. When 8 detects that the voltage input to 3 1 has reached the specified voltage, voltage 8 outputs the specified signal. When 1 receives a signal from voltage 1, it causes (sets) for a fixed time. Fig. 33 shows a configuration in which a pulse configured in software using a dedicated C or the like is provided as part of control 1 so that the first pulse signal is output in response to the signal from voltage 8 . Alternatively, the present invention is not limited to the above configuration, and the configuration may be such that the force from the voltage 18 is input to the main control 2 configured as follows, and the second pulse signal is output in software. It is preferable to set the fixed time to be a little shorter than the period of the wave number source.

8

Next, when starting the operation in which the main becomes (state) after the above-mentioned fixed time has elapsed, the control 13 causes the auxiliary 17 to remain (for example, several hundreds) for a fixed time. If the auxiliary 17 becomes (state) a little later than 33, after detecting that the state has changed to (state), the number of two pulses for a predetermined time is set to 17 for a fixed time. An example is shown as a 2-pulse control section that outputs. Alternatively, the control city 2 may output a pulse signal to the auxiliary 17 that is longer by a fixed time than the pulse output to. Alternatively, an extension circuit may be configured using a diode capacitor. In the implementation, the timing of the main part is the same as in 4 and will be explained. Figure 3 a) shows the case where the power factor is, and Figure (b) shows the case where the power factor is not 1.

()

Next, 2 of the load devices used in the five states will be explained. 35 is a route diagram showing the composition of load 11 related to. 3 Compared with 35, the load according to state 2 further includes 2 for detecting the current flowing through auxiliary 7. The others are the same.

8

As explained in, it is intended to detect the crossing point of the auxiliary current, which is inherently not intended to be energized, and is expected to be composed of small switch elements. However, if the wave number shifts in a commercial source, or if the load device is operated for 5 H and 6 H, the time between the disappearance of the current and the current crossing becomes longer, and the load current becomes longer. Energization was started before the time was small enough. In addition, even if the load is the same as when it is connected, the energization becomes large, and the switch that constitutes the auxiliary may be damaged. Therefore, detects the current that flows to 17 by the current, and when current exceeding the current that can be tolerated by auxiliary 1 flows, only time is allowed to (state), and when that becomes (state), Help 1-7. Thus, by repeatedly switching 1 auxiliary 17, loss of the auxiliary 17 switch is prevented and compatibility with commercial sources and load is improved. Figure 3 shows the load for 1.

87

(3)

Next, 3 of the load devices used in the five states will be explained. 37 is a route diagram showing the composition of the load related to. 3 In comparison, “Load 3” is basically the same as load H according to the above, except that the switches comprising are composed of bidirectional transistors. Note that 3 conforms to the composition of the load shown in 5 but is not limited to this, and may be configured similarly to the load H shown in 88. 88

38 shows the formation of a bi-directional transistor. Such a transistor H g ec ron ob y ran s or is used as a channel, using two gas layers generated on the AGaN GaN surface as the channel, and on the surface, the electrode DD connected to the power supply 3 in each row and the electrode DD A control (gate) G is formed for the electrode D and the electrode so that a high voltage can be maintained when the energization is turned off. For example, a Schottky pole is used as G.

9

When (is in the state, the control G has a 3 to w level. Although the number is marked, the number of diodes is less than the number of 1s. Here, the non- (state) can be reliably maintained if it is sufficiently higher than the diode part for switching () (state) of 1 1. One, Lord 1 () above

Do the same as in case 3. Therefore, the source of pressure can be directly controlled by the control city 3 driven by the V signal. In addition, quantification of 2 can be realized by using HMT with electron mobility. ()

Next, we will explain the load devices used in the five states. Figure 3 is a route diagram showing the composition of load K related to. The load K related to is basically the same as the load H˜ described in 3 above, except that the constituent switch 1 is composed of a new bidirectional transistor. Note that 39 conforms to the composition of the load shown in 3 shown in 7 but is not limited to this. It is configured in the same way as the load H shown in 33 or the load 1 1 shown in FIG. Moyo. Is a plan view showing the configuration of the switch c, and is a A A side view thereof. As shown in Fig. 12, 12 of switch c is 1 2 and

It is composed of GaN A GaN 2 stacked on top of 2. In this switch 1G, a two-gas layer generated on the A GaN GaN surface is used as the channel. As shown in Fig. 1, 1 d 12 d is formed with 1 D 2 D2 connected to the power supply 2 3 in a row, and an intermediate S that is intermediate to the D and 2 D positions. The Further, a control (gate) G is laminated on the intermediate S. For example, a Schottky pole is used. D

2D is a shape having a number of 1,,,,, arranged in parallel to each other, and the electrodes arranged in a shape are arranged so as to face each other. S G is placed between the electrodes arranged in the shape of each other, and has a shape () similar to the shape of the space formed between the electrode parts.

2

Next, the structure of the transistor constituting the switch 1C will be described. As shown in Fig. 2, D 2 D are arranged so that their centers are collinear, the middle S response part and the G response part are respectively for 12 columns of D 2 D2 It is provided in parallel. 5 distances between the 1 S 1 D 2 D2 1 intermediate S response part and the G response part in the direction are set to a distance that maintains the specified pressure. The same is true for the direction to be corrected, that is, D 1 2 D 2 direction. In addition, these other

3 23 ・・ The same applies to. That is, the intermediate SG is arranged in a position that maintains a predetermined pressure with respect to D D Z 93

In this way, the middle of the D position and the middle S that is the middle of the D position are connected to this S, and G for controlling the middle S maintains a predetermined pressure for 1 DD. For example, if D and D2 are, and the bidirectional switch is, that is, when G is marked with a V sign, the current is at least between D and control S. Disconnected reliably (current is stopped under (gate) G). On the other hand, when the bidirectional switch is turned on, that is, when G is marked with a voltage higher than a predetermined value, as indicated by the mark, D (1 3 ・), intermediate S ・ D (1 1 3 ・・・The current flows through the path, and vice versa.

9

In this way, by forming an intermediate S in a position where a predetermined pressure is maintained with respect to D 2 D, the switch can be reliably operated even when the signal pressure to control G is reduced to the minimum level. Can be realized and on-resistance can be realized. By using this switch 1C to configure the control signal, the reference (GND) is set to the same potential as the intermediate S, and the source of pressure is directly controlled by the control 13 driven by the V signal. be able to. In addition, in the above case, since the voltage under the effect of 12 diodes is not affected, even if the pressure for switching () (state) of 1 is reduced, it is possible to reliably maintain non- (state). it can. Furthermore, in the transistor element using the two gas layers generated on the surface as the channel, since it is in the on-reciprocal relationship at the time of the pressure that makes the element invisible, it is possible to reduce the pressure because the pressure can be reduced. To achieve a low load, and to realize the quantification of the load it can. (6)

Next, the load devices according to the six states will be described. Fig. 6 is a route diagram showing the composition of loads related to six states. The load related to the state is basically the same as the loads H to K related to the above-mentioned five states, except that a cross 3 is provided in 3 and a pulse is provided in the control 13. 4 is the load shown in 35

Although not limited to this, it may be configured in the same manner as the load H shown in 3, the load 3 shown in 37, or the load K shown in FIG. 3. . The cross 23 detects the cross point of the load current and outputs a cross signal indicating that to the first pulse. When 3 pulses receive the force of the zero cross signal from zero cross 2 3, 3 pulses are output. The 3 pulses are received from the cross at zero cross 23, and rise for 3 fixed time. 3 The fixed time is set to be the full load current period.

7

3 pulses output from pulse 3 pulse output from pulse 1 are input to control 3. Mitsu 3 has AND 25 and takes 3 pulses and outputs to OR via OR 5. OR 2 is provided after AND 5 of control 1 3. When OR 2 receives the power of the signal from the current from AND 5 described above, it protects Auxiliary 7 by shortening for a short time.

8

As mentioned above, is closed only for the fixed time that the pulse rises and the 3 fixed time that the third pulse rises. The 3 pulse rises when the zero cross 3 detects the crossing point, and falls in the third fixed period shorter than the load current cycle, so the timing to detect the end of the buff capacitor, that is, the fixed time starts Even if the timing deviates later, the power wave number crossing point will not be exceeded and 1 will not be set. As a result, half-cycle charging can be performed reliably, and operation can be fixed.
