Description
Technical field
The present invention relates to alternative electric generation output be divided into forward and negative sense, for battery charge with power supply with to the control circuit that the power supply of lamp power supply provides, particularly relate to the control circuit that can stably power to lamp.
In addition, the invention still further relates to and use alternating current generator that battery is carried out electrically-charged battery charger, particularly work as battery and be under the open-circuit condition, protection connects the connection load protection circuit of load.
Background technology
Generally, when using the alternative electric generation output by the electrical generator that driving engine drove of motor bike etc., all have and be used for to the power supply of battery charge and light the control circuit that the power supply of headlight etc. provides.
In this control circuit, when the actuating speed of electrical generator becomes high speed, the driving voltage peak value of lamp just increases, in order to prevent the overtension of lamp, in case generating voltage increases, just drive the half-wave output of lamp, reduce available voltage (with reference to Fig. 2 (b), Figure 19 (b), Figure 19 (c)) by intermittent disconnection.
Owing in this control circuit, can produce problems such as lamp flicker, so the technology of record in the patent documentation 1 has just been arranged.According to this technology, when the available voltage of lamp surpassed threshold value, just start delay circuit, reduced the driving voltage peak value of lamp at the time of the thyratron conducting by postponing the control lamp.
Open in the technology of 2001-93680 communique record the spy, in case the actuating speed of electrical generator reaches some degree, the half-wave composition after the charge power supply conducting just of storage battery, half-wave composition for other only carries out the work of level shift without exception, under the excessive situation of the half-wave composition peak value behind the level shift, if not intermittent disconnection half-wave waveform, the power of power supply will be excessive, thereby first kind of such problem of lamp flicker will occur.
In addition, all the time, the battery charging plant (for example opening the 2001-93680 communique with reference to the spy) that uses alternating current generator to carry out battery charge is known.In this battery charging plant, be at storage battery under the situation of open-circuit condition, because can be to the regulating control output voltage identical with the output voltage of alternating current generator, so under the situation that the alternating current generator horsepower output transfinites or during high rotating speed, just may take place to the regulating control output HIGH voltage, damage the problem that connects load.
Therefore, in order to protect the connection load, adopted following method in the past.Wherein a kind of method is to adopt the such circuit of Fig. 9, and the output voltage of alternating current generator 1103 is carried out the processing of intermittent disconnection, with control action at the effective voltage value that connects in the load 1603.Specifically, such circuit for example is made of circuit shown in Figure 9, and it is at storage battery under the situation of open-circuit condition, can carry out the control of intermittent disconnection to the output voltage of alternating current generator 1103.
Wherein, the Zener voltage of Zener diode Z23 is set at voltage (rated value) height than storage battery, when storage battery is under the open-circuit condition, when the output voltage of regulating control 1203 is high, just after diode D21 passes through Zener diode Z23, resistance, charge to cond C21 again.Then, when when cond C21 charges, utilize this voltage to make transistor Q21 keep conducting state, and, thyratron SCR22 is disconnected by transistor Q22, Q23 are disconnected.Like this, just can cut off output to the regulating control 1203 that connects load 1603 supplies.
In addition, when reducing to the electrically-charged electric charge of cond C21, when reducing current potential, transistor Q21 just can not keep conducting state, is at transistor Q21 under the situation of off-state, though thyratron SCR22 is in conducting state, and provide output voltage to connecting load 1603 by regulating control 1203, still, if this moment, storage battery was in open-circuit condition, just will follow and original same path, once more cond C21 be charged.Therefore, by continuing to keep such state, the output voltage that intermittent disconnection provides to connection load 1603 from regulating control 1203 just can the effective voltage value of control action in connection load 1603.
In addition, when storage battery connects and the voltage between charge point (the A point among Fig. 9)-earth point (the E point among Fig. 9) during the storage battery open circuit, the voltage between storage battery (the B point among Fig. 9)-earth point (the E point among Fig. 9), the voltage between lamp (the L point among Fig. 9)-earth point (the E point among Fig. 9), the charging valtage of cond C21, the gate signal of thyratron SCR21, the gate signal of thyratron SCR22, all be illustrated among Figure 10 a and Figure 10 b.From shown in Figure 10 a as can be seen, though under storage battery bonded assembly state, the voltage control between storage battery (the B point among Fig. 9)-earth point (the E point among Fig. 9) in suitable value, but, when storage battery is in open circuit, just shown in Figure 10 b, part by the state of intermittent disconnection under, charge point
Voltage between (the A point among Fig. 9)-earth point (the E point among Fig. 9) shows as storage battery
Voltage between (the B point among Fig. 9)-earth point (the E point among Fig. 9).
Figure 11 represents the another kind of mode of intermittent disconnection control.In this case, the Zener voltage of Zener diode Z31 is set at than battery tension (rated value) height, under storage battery is in open-circuit condition, when the voltage of regulating control 1204 output is high,, charge by Zener diode Z31, resistance from diode D31 to cond C31.And, utilize this voltage to make transistor Q31 keep conducting state when when cond C31 charges, and disconnect thyratron SCR32.Like this, just can cut off output to the regulating control 1204 that connects load 1604 supplies.
When in addition, storage battery connects and the voltage between charge point (the A point among Figure 11)-earth point (the E point among Figure 11) during the storage battery open circuit, voltage, the lamp (the L point among Figure 11)-earth point between storage battery (the B point among Figure 11)-earth point (the E point among Figure 11)
Voltage between (the E point among Figure 11), the charging valtage of cond C31, the gate signal of thyratron SCR31, the gate signal of thyratron SCR32 are all shown in Figure 12 a and Figure 12 b.From shown in Figure 12 a as can be seen, under the storage battery coupled condition, voltage control between storage battery (the B point among Figure 11)-earth point (the E point among Figure 11) is in suitable value, and when storage battery is opened a way, then shown in Figure 12 b, voltage between charge point (the A point among Figure 11)-earth point (the E point among Figure 11), part by the state of intermittent disconnection under, show as the voltage between storage battery (the B point among Figure 11)-earth point (the E point among Figure 11).
Figure 13 represents existing another kind of mode.This mode is when storage battery is in open-circuit condition, conducting thyratron SCR43, the mode of the output voltage of regulating control 1106 being carried out peak clipping (peak cut) control.Wherein, the Zener voltage of Zener diode Z43 is set at than battery tension (rated value) height, under storage battery is in open-circuit condition, when the output voltage of regulating control 1106 is high, pass through Zener diode Z43, resistance from diode D41, utilize to send gate signal, make the output short-circuit of alternating current generator 1105 by thyratron SCR43.Therefore, in this mode, the output voltage peak value of storage battery when open circuit regulating control 1106 is just near the zener voltage of Zener diode Z43.
In addition, when storage battery connects and the voltage between charge point (the A point among Figure 13)-earth point (the E point among Figure 13) during the storage battery open circuit, the voltage between storage battery (the B point among Figure 13)-earth point (the E point among Figure 13), the voltage between lamp (the L point among Figure 13)-earth point (the E point among Figure 13), the gate signal of thyratron SCR41, the gate signal of thyratron SCR42, the gate signal of thyratron SCR43, all shown in Figure 14 a and Figure 14 b.From shown in Figure 14 a as can be seen, under storage battery bonded assembly state, voltage control between storage battery (the B point among Figure 13)-earth point (the E point among Figure 13) is in suitable value, and when storage battery is opened a way, then shown in Figure 14 b, voltage between charge point (the A point among Figure 13)-earth point (the E point among Figure 13) shows as the voltage between storage battery (the B point among Figure 13)-earth point (the E point among Figure 13) near the Zener voltage of Zener diode Z43.
Usually, in the regulating control of the voltage of adjusting storage battery and lamp, storage battery is carried out open type control, that is, when battery tension is higher than specified value just with its open circuited control.In the past, owing to use thyratron to carry out this open type control, so, even be higher than at battery tension under the situation of specified value, can not directly disconnect., as countermeasure, do not having under the state of storage battery, perhaps storage battery becomes under the bad state of change of high resistance, use the mode or the peak clipping mode of above-mentioned intermittent disconnection for this reason.
; as it is; output load at two-wheel car increases; and under the situation that the output of alternating current generator also increases thereupon; even when storage battery is opened a way, carry out the control of intermittent disconnection; though can reduce effective value, peak voltage has increased, exist the problem of action of high voltage in load.In order to prevent this situation, if prolong the time of intermittent disconnection, the ignition device of CDI and so on just misfires, and will produce motor bike can not move as usually, perhaps second kind of problem of lamp flicker and so on.
Under the situation of this external peak clipping mode,, reduced, so can produce deepening or the out-of-run problem of load such as lamp to the voltage of load output because effective voltage value falls lowly excessively.Further, owing to made the big alternating current generator short circuit of output, increase second kind of such problem so the regulating control cal val can further be produced.

Above-mentioned control circuit 2 has thyratron 7-1,7-2.The anode of thyratron 7-1 is connected on the input terminal 3, and its negative electrode is connected on the first power supply terminal 4-1, and the half-wave composition of the forward of alternative electric generation output is exported to the first power supply terminal 4-1.The negative electrode of thyratron 7-2 is connected on the input terminal 3, and its anode then is connected on the second power supply terminal 4-2, and the half-wave composition of the negative sense of alternative electric generation output is exported to the second power supply terminal 4-2.
The time that trigger current is extremely gone up in first power control circuit 8-1 control thyratron 7-1 control, and control is to the power supply of the first power supply terminal 4-1.Equally, the time that trigger current is extremely gone up in second source control circuit 8-2 control thyratron 7-2 control, and control is to the power supply of the second power supply terminal 4-2.
In second source control circuit 8-2, behind the voltage of the half-wave composition of the forward on the voltage detecting circuit 801 detection input terminals 3, export as detection signal Vd.The shift voltage Vs of displacement (shift is also referred to as drift or skew) potential storage circuit 802 storages and maintenance regulation.This shift voltage Vs is redefined for the value of the charging valtage Vc that is equivalent to storage battery 5.Voltage shift circuit 803 as the waveform of the half-wave composition of detection signal Vd input only to shift voltage Vs of active potential displacement.Integrating circuit 804 during as Vd1, is carrying out integration to the output signal of voltage shift circuit 803 to the waveform after the active potential displacement as output signal Vd1 input.The integration output of integrating circuit 804 is as indicating delay time Vt to output in the control utmost point control circuit 805.Control utmost point control circuit 805 is transported to the control utmost point of thyratron 7-2 to trigger current, and by according to the time of indicating Vt control thyratron 7-2 conducting delay time, control is from the power supply of the second power supply terminal 4-2.
Below, the work of this control circuit 2 is described.Fig. 2 is the sequential chart of the waveform of expression control circuit 2 each several parts.In addition, Fig. 3 represents the waveform of existing control circuit each several part, the fluctuation composition of the output voltage V 2 of Δ V indication lamp 6 one sides.In Fig. 2,3, voltage (the output voltage V g of electrical generator 1) on figure (a) the expression input terminal 3, electric current (the outgoing current Ig of electrical generator 1) on figure (b) the expression input terminal 3, the voltage (output voltage V 2 of lamp 6 one sides) on figure (c) the expression second power supply terminal 4-2.

Under the situation that allows thyratron 7-1 conducting, in the moment that half-wave composition Wp rises, thyratron 7-1 conducting (Fig. 2: A), flow to forward (Fig. 2: B) in a large number as the outgoing current Ig of the charging current of storage battery 5.When outgoing current Ig was 0, thyratron 7-1 just disconnected.In addition, in thyratron 7-1 conduction period, output voltage just is biased to the charging valtage Vc of storage battery 5.
When thyratron 7-1 disconnected, the half-wave composition Wn of negative sense rises, and (Fig. 2: C), as the back was narrated, indicating Vt delay time was 0, so control utmost point control circuit 805 rises half-wave composition Wn, and made thyratron 7-2 conducting.So outgoing current just flows to lamp 6 one side (Fig. 2: D).
On the other hand, under the situation that does not allow thyratron 7-1 conducting,, also still keep disconnecting waveform (Fig. 2: E) of the sinusoidal waveform of the voltage of half-wave composition Wp when non-loaded even the half-wave composition Wp of thyratron 7-1 rises.In addition, not conducting of outgoing current Ig (Fig. 2: F).At this moment, with the voltage of voltage detecting circuit 801 detection half-wave composition Wp, export to voltage shift circuit 803 as detection signal Vd.This detection signal Vd to one of active potential displacement and the cooresponding shift voltage Vs of charging valtage Vc, generates signal Vd1 by voltage shift circuit 803 thus.This signal Vd1 represents to be equivalent to surpass the waveform that exceeds part (drawing the part of oblique line among Fig. 2) of the charging valtage Vc of half-wave composition Wp, by this signal Vd1 being carried out integration, just obtained and the above-mentioned proportional value of area that exceeds part with integrating circuit 804.The value that obtains like this as indicating Vt delay time, is exported to control utmost point control circuit 805.
Because control utmost point control circuit 805 is the half-wave composition Wn from negative sense when rising, according to the time conducting thyratron 7-2's that indicates delay time Vt to postpone, so keep and area proportional delay time of the Td that exceeds part, to the outgoing current Ig of lamp 6 one sides output rising (Fig. 2: G).Therefore, in when charging because output voltage is biased to charging valtage Vc, thus delay time Td=0, that is, be not that half-wave composition from negative sense begins to postpone when rising, but make (the Fig. 2: D) that rises to the outgoing current Ig of lamp 6 one sides.On the other hand, when not charging, then keep and above-mentioned area proportional delay time of the Td that exceeds part, rise to the outgoing current Ig of lamp 6 one sides.Like this, just can (Fig. 2: D) be benchmark, (Fig. 2: peak value G) makes it even to adjust outgoing current Ig when not charging with the outgoing current Ig in when charging.In addition, shown in Fig. 2 (c), identical with shape to the outgoing current Ig of lamp 6 to the shape of the output voltage V 2 of lamp 6.
More than, embodiments of the invention are described in detail, but concrete formation is not to only limit to this embodiment that it also is included in and does not break away from the present invention and want design modification in the point range.For example, if adopt the cooresponding shift voltage Vs of charging valtage Vc with storage battery 5 as predefined fixed value, it being added in mode on the shift voltage memory circuit 802, is being favourable simplifying aspect the circuit formation.In addition, also can adopt with shift voltage Vs as the mode of importing with the corresponding change value of the charging valtage Vc of reality.In this case, for example also can adopt thyratron 7-1 conducting, the value when detecting output voltage V g with charging valtage Vc biasing generates shift voltage Vs according to detected value, is entered into the mode in the shift voltage memory circuit 802.Like this, just can reflect the control of the actual charging valtage Vc of storage battery 5, also have the advantage of raising to the control accuracy of the degree of uniformity of the output of lamp 6 one sides.

Alternating current generator 1001 for example is the alternating current generator of motor cycle engine direct drive, exports mutually and the corresponding alternating-current voltage/AC voltage of rotating speed from each.First delay time generating unit 1002 according to the signal of narrating later from voltage detection department 1005, at the voltage ratio specified value height of storage battery 1006, when storage battery 1006 is open-circuit condition, input forms the big or small corresponding delay time with the alternating-current voltage/AC voltage of importing from the interchange output of alternating current generator 1001.Specifically, for to connecting the half-wave composition that load 1007 provides, the magnitude of voltage of the half-wave composition before the half period is carried out integration, produce delay time, then offering thyratron control part 1003 delay time that produces.
The arcing of the thyratron 1008 on 1003 controls of thyratron control part are arranged in series in storage battery 1006 and are connected load 1007, according to from first delay time generating unit 1002 and delay time of generating unit 1004 inputs second delay time narrated later, the arc time of control thyratron 1008.Second delay time generating unit 1004 according to signal from voltage detection department 1005, be higher than under the situation of specified value at the voltage effective value that provides to connection load 1007, generate second delay time longer, it is outputed in the thyratron control part 1003 than first delay time.Then, in order to make the voltage effective value that offers connection load 1007 stable, carry out intermittent disconnection control in this way.Voltage detection department 1005 detects the terminal voltage of storage battery 1006, judges whether this terminal voltage is higher than predetermined specified value.
Fig. 5 is the figure of the connection load protection circuit structure of more detailed expression second embodiment.
As shown in Figure 5, the connection load protection circuit of second embodiment comprises: alternating current generator 1101, regulating control 1201, storage battery 1701, connection load 1801, headlight 1001 and taillight 1011.In addition, regulating control 1201 comprises following each several part: battery tension adjust circuit 1301 (voltage detection department 1005 that is equivalent to Fig. 4), intermittent disconnection control part 1401 (be equivalent to Fig. 4 second delay time generating unit 1004), phase control circuit 1501 (be equivalent to Fig. 4 first delay time generating unit 1002), thyratron control part 1601 (the thyratron control part 1003 that is equivalent to Fig. 4), modulating voltage control circuit 1901.
In addition, battery tension adjustment circuit 1301 is made of Zener diode Z1, Z2 and the resistance of the Zener voltage with the rated value that is equivalent to storage battery 1701, and intermittent disconnection control part 1401 then comprises resistance R 6, cond C1 and the diode D2 of Zener diode Z3, formation time constant circuit.In addition, phase control circuit 1501 comprises: the resistance R 2 of Zener diode Z4, resistance R 5, diode D5, formation time constant circuit, cond C3, Zener diode Z5, diode D6, transistor Q4, diode D9 and cond C2.
Below, with reference to Fig. 6 a and Fig. 6 b the circuit working of Fig. 5 is described.At first, under the situation that has connected storage battery 1701, voltage between storage battery among Fig. 6 a (B)-earth point (E), owing to control the control utmost point signal of thyratron SCR2 with thyratron control part 1601, so its magnitude of voltage changes in specified value, the terminal voltage of storage battery 1701 can not surpass the Zener voltage of Zener diode Z4.Therefore, the base stage of the transistor Q4 in phase control circuit 1501 does not provide voltage, becomes off-state.At this moment, though cond C3 was in the negative cycle of alternating current generator 1101, but the circuit that constitutes by diode D6, Zener diode Z5, cond C3, resistance R 2, diode D5 carries out charge charging to it, because transistor Q4 is open circuited, so do not exist with the loop of the negative voltage after the charging to the C3 discharge, time constant circuit is not worked.On the other hand, shown in Fig. 6 a, in the negative cycle of alternating current generator 1101, modulating voltage control circuit 1901 is by providing control utmost point signal, the voltage between headlight 1001, taillight 1011 generation lamp (L)-earth points (E) to thyratron SCR1.
Then, at the state that does not have storage battery 1701, perhaps storage battery 1701 becomes under the bad situation, adjusts the work of circuit 1301 by battery tension, and transistor Q1 is disconnected.When transistor Q1 was in off-state, the output of alternating current generator 1101 just through diode D4, resistance R 1, diode D8 and resistance R 4, made the transistor Q2 conducting of thyratron control part 1601.
When transistor Q2 conducting, the output of alternating current generator 1101 just by between emitter-base stage of diode D4, transistor Q3, via resistance R 3, diode D7, flows to transistor Q2, thereby makes transistor Q3 conducting.When transistor Q3 conducting, the output of alternating current generator 1101 offers thyratron SCR2 to control utmost point signal just via diode D4, transistor Q3, resistance, diode D3.Like this, the output of alternating current generator 1101 just offers storage battery 1701 and is connected load 1801.
When thyratron SCR2 conducting, just the voltage higher than specified value is offered storage battery 1701 and is connected load 1801.So, just, charge to cond C2 by Zener diode Z4, resistance R 5.In addition, at this moment, the Zener voltage of Zener diode Z4 is set at the maxim height than the adjustment voltage of storage battery 1701.
When cond C2 charged, transistor Q4 was just because of this charging valtage conducting.When transistor Q4 conducting, because the negative voltage after cond C3 charging was in the positive period of alternating current generator 1101, formation is via diode D9, between collecting electrode-emitter of transistor Q4, between the charge point of alternating current generator 1101 (A)-earth point (E), diode D4, the discharge loop of resistance R 1, thereby just work of time constant circuit, be equivalent in the time of this discharge time, by making via diode D4, resistance R 1, diode D8, resistance R 4, the ON time of transistor Q2 is postponed, delay provides control utmost point signal to thyratron SCR2, comes control phase.
In addition, when the rotating speed of alternating current generator 1101 accelerates, though the output voltage of alternating current generator 1101 also increases, but, if the output voltage of alternating current generator 1101 also increases, then also increase, because this influence to the electrically-charged negative voltage of cond C3, provide control utmost point signal also to postpone to thyratron SCR2, so can not provide high potential to storage battery 1701, connection load 1801 from thyratron.
In addition, adjust the maxim height of voltage but lower by the Zener voltage of Zener diode Z4 being set at than the output voltage of thyratron SCR2 than storage battery, when storage battery 1701 open circuits, can all cond C2 be charged in each cycle, owing to can keep the conducting state of transistor Q4, so each cycle can be implemented phase control.
In addition, for control to storage battery 1701 be connected load and provide the effective value voltage of voltage, also can in the very short delay time that control utmost point signal is being provided to thyratron SCR2, use intermittent disconnection control simultaneously.Specifically, after charging,, transistor Q2 is disconnected, to carry out intermittent disconnection control by keeping transistor Q1 conducting via Zener diode Z3 and 6 couples of cond C1 of resistance R.In addition, as mentioned above, in a second embodiment, owing to implemented phase control, so the number of times of intermittent disconnection is few.Therefore can not produce the peculiar problem of intermittent disconnection.
Fig. 7, Fig. 8 a and the load protection circuit that is connected shown in Fig. 8 b are the variation of connection load protection circuit shown in Figure 5, and the surrounding structure difference of the modulating voltage control circuit 1902 of voltage is provided to headlight 3002, taillight 1012.The connection load protection circuit of present embodiment also can be used for circuit shown in Figure 7.
Therefore,, after carrying out phase control,, both reduced peak value, reduced intermittent disconnection, reduced the cal val of regulating control again to the voltage of load output by postponing the arc time of thyratron according to present embodiment.
The 3rd embodiment
Below, with reference to the description of drawings third embodiment of the present invention.
Figure 15 is the block diagram of the lamp lighting control circuit overview of expression the 3rd embodiment.The lamp lighting control circuit of the 3rd embodiment is separated into the half-wave composition of forward and negative sense to alternative electric generation output, and a kind of half-wave composition wherein to the charging terminal output of storage battery, and is exported to lamp to another kind of half-wave composition by thyratron.As shown in figure 15, above-mentioned lamp lighting control circuit comprises: electrical generator 2001, thyratron 2002, lamp 2003, control utmost point control circuit (being equivalent to the thyratron control setup) 2004, phase control circuit (being equivalent to phase control evice) 2005, modulating voltage are adjusted circuit (being equivalent to the modulating voltage setting device) 2006, battery tension control circuit 2007 and storage battery 2008.
Below, describe the work of circuit each several part in detail with reference to Figure 16～Figure 18.Wherein, Figure 16 is the figure of circuit structure of the lamp lighting control circuit of expression the 3rd embodiment, the waveform of Figure 17 and Figure 18 indication circuit each several part.
The work of phase control circuit
With Figure 16 and Figure 17 the work of phase control circuit is described.In addition, in the 3rd embodiment, explanation be the situation that the half-wave of the below of alternating current generator output is supplied to lamp 2003.As shown in figure 16, phase control circuit comprises cond C54, diode D54, Zener diode Z56 and resistance R 54.
This circuit by cond C54, diode D54, Zener diode Z56 and resistance R 54, constitutes path through GND when electrical generator 2001 output forward half-waves, charge to cond C54.Zener diode Z56 than its Zener voltage hour, stops electric current to pass through at the outgoing level of electrical generator 2001, directly makes thyratron SCR51 arcing.In addition, this moment cond C54 with the mouth of electrical generator 2001 for just, the other end charges for bearing.
Then, when electrical generator 2001 output negative sense half-waves, form emitter,, make transistor Q53 conducting through returning the path of electrical generator 2001 after base stage, diode D56, the resistance R 55 again from transistor Q53.When transistor Q53 is in conducting state, just form between the emitter-collecting electrode by electrical generator 2001, transistor Q53, after the resistance R 63, diode D55, return the discharge loop of cond C54 again, the electric charge that is stored among the cond C54 is discharged.Then, when the discharge of cond C54 finished, transistor Q51 provided control utmost point signal by diode D51 to thyratron SCR51 with regard to conducting.
That is, when the output of electrical generator 2001 forwards was higher than the Zener voltage (Vc of Figure 17) of Zener diode Z56, electric charge was to cond C54 charging, made the length (the Δ T of Figure 17) that arc time of thyratron SCR51 only prolongs the charge discharge time.
With Figure 17 above-mentioned work is described below.Figure 17 is the sequential chart of the lamp lighting control circuit each several part waveform of expression the 3rd embodiment.In Figure 17, (a) the output voltage V g of expression electrical generator 2001, the outgoing current Ig of (b) expression electrical generator 2001, the output voltage V 2 of (c) indication lamp voltage-regulating circuit 2,006 one sides.In addition, Vc represents the Zener voltage of Zener diode Z56 among the figure.
With reference to Figure 17, when non-loaded, the output voltage V g of electrical generator 2001 is the sinusoidal waveform of representing with long and short dash line among Figure 17 (a).Not when storage battery 2008 charges, the voltage of half-wave composition Wp approaches waveform (Figure 17: E) of the sinusoidal waveform when non-loaded.In addition, not conducting of outgoing current Ig this moment (Figure 17: F).In addition, when the voltage of half-wave composition Wp surpasses threshold value Vc (drawing the part of oblique line among Figure 17),, use with the proportional electric charge of the area of above-mentioned excess portion and charge to cond C54 just by means of this signal.
Then, when the output of electrical generator 2001 becomes the half-wave composition Wn of negative sense, just form above-mentioned discharge loop, and keep and be stored in electric charge proportional delay time of Δ T among the cond C54, carry out the arcing of thyratron SCR51.In the 3rd embodiment, owing to be when the half-wave composition Wn of negative sense rises, conducting thyratron SCR51 in the time that Δ T postpones according to delay time, thereby can keep area proportional delay time of Δ T with excess portion, make (the Figure 17: G) that rises to the outgoing current Ig of lamp 2,003 one sides output.Therefore, during storage battery 2008 charging because the output voltage of electrical generator 2001 is below threshold value Vc, thus delay time Δ T=0, that is, the outgoing current Ig (Figure 17: D) that provides to lamp 2003 is provided the rising from the half-wave composition of negative sense without delay.
On the other hand, when storage battery 2008 did not charge, area proportional delay time of the Δ T of maintenance and above-mentioned excess portion rose to the outgoing current Ig of lamp 2,003 one sides.Like this, and the outgoing current Ig in the time of just charging with storage battery 2008 (Figure 17: D) be benchmark, the outgoing current Ig when adjustment is not charged (Figure 17: peak value G), so that it is even.In addition, shown in Figure 17 (c), identical with shape to the outgoing current Ig of lamp 2003 to the output voltage V 2 of lamp 2003.
The uniformization work of effective value
Below, the work of effective value (RMS) uniformization of the voltage that provides to lamp is provided with Figure 16 and Figure 18 explanation.
Under the situation of the output voltage stabilization of electrical generator 2001,, just can make the voltage uniformization that provides to lamp 2003 by making above-mentioned phase control circuit 2005 work., the output voltage of electrical generator 2001 rotating speed of being subjected to electrical generator 2001 etc. influences and changes.Therefore, in order to prolong the life-span of lamp 2003, it is desirable to control its effective value.So, in modulating voltage is adjusted circuit 2006, have the function of the effective value of the voltage that control provides to lamp 2003.
Specifically, when the output voltage of electrical generator 2001 is negative sense, thyratron SCR2001 arcing, and when when lamp 2003 provides voltage, will produce and the identical difference of potential of voltage that offers (between the L and E among Figure 16) between lamp 2003 and the earth point.So, can utilize this voltage that cond C57 is charged.And, when the voltage of cond C57 surpasses the Zener voltage (threshold value (Z58) of Figure 18 (b)) of Zener diode Z58,, transistor Q53 is disconnected just by making transistor Q54 conducting, lamp 53 is extinguished.
In addition, owing to be to be undertaken by the arcing of thyratron SCR51 to lamp 53 power supply, so, when lamp 53 provides voltage, even transistor Q54 conducting, as long as the control utmost point of thyratron SCR51 reverse bias not just can continue to provide voltage.
The time constant that is determined by cond C57 and resistance R 57 is depended in the discharge of cond C57.Therefore, the discharge of cond C57 is all the time towards same direction.Shown in the H of Figure 18, the output voltage of electrical generator 2001 uprises, like this, when the voltage that provides to lamp 2003 (J among Figure 18) when becoming big because cond C57 charges with this voltage, so just the terminal voltage after cond C57 charges improved.
On the other hand, as mentioned above, because the discharge of cond C57, be to carry out according to the time constant of cond C57 and resistance R 57 decisions, all the time towards same direction, so the output voltage at electrical generator 2001 is in the next cycle of negative sense, even in the time of phase control circuit 5 work, transistor Q54 also is in conducting state.Therefore, the time of transistor Q53 conducting, just the time of thyratron SCR51 arcing, only postpone Δ t (I among Figure 18).The magnitude of voltage (K among Figure 18) that provides to lamp 2003 like this, just has been provided.So, be applied under the big situation of voltage ratio average voltage on the lamp 2003, in next cycle, because the arc time of thyratron SCR51 is further postponed, and the magnitude of voltage that provides to lamp 53 has been provided, so, even if under the temporary transient situation about changing of the output voltage of electrical generator 2001, for example, also can make the voltage effective value uniformization that provides to lamp 2003 in the unit time.
In addition, adjust in the circuit at the modulating voltage of Figure 16, Zener diode Z58 is identical with the Zener voltage of Zener diode Z59, compares with the resistance value of resistance R 55, and the series impedance of resistance R 61 and resistance R 60 just becomes very little value.This be because, aspect the relation of during above-mentioned phase control must the half period in the output of electrical generator 2001, carrying out, at first to use the path of resistance R61, resistance R 60, cond C57 is carried out fast charge.
In addition, the circuit that is made of Zener diode Z60 and resistance R 55, resistance R 56 for example, is a kind of by turning on of lamp 53 etc. and make protective circuit under the situation of the voltage increases that lamp 2003 provides.Specifically, Zener voltage at Zener diode Z60 has reached threshold value, the voltage that produces has surpassed under the situation of Zener voltage of Zener diode Z60, resistance R 55 and resistance R 56 become and are connected in parallel, C57 charges to cond, so just can transistor Q53 be disconnected, control the magnitude of voltage that is applied on the lamp 2003 by making transistor Q54 conducting.
Therefore,,, adjust size, just can improve the homogeneity of magnitude of voltage, prevent flicker of lamp or the like to the half-wave composition of lamp output according to the size of the half-wave composition before the semiperiod according to the 3rd embodiment.In addition, can also make the voltage that is applied on the lamp even with simple circuit configuration.
More than embodiments of the invention are had been described in detail, but concrete structure is not limited to these embodiment, also should be included in the design modification in the scope that does not break away from main points of the present invention.For example, in the present embodiment, illustrated that the forward half-wave composition with electrical generator output charges to storage battery, produce the example that voltage is provided to lamp with negative sense half-wave composition, but be not to only limit to this, also can charge to storage battery, and generate the voltage that offers lamp with forward half-wave composition with negative sense half-wave composition.
