Apparatus and method for power saving auto potential transformer}

The present invention relates to a power-saving automatic transformer, in particular, having a hall sensor for detecting the load amount of the secondary coil by making the primary coil into a lottery, and performs a multi-stage division operation in order to control the supply current of the primary coil. The present invention relates to a power-saving autotransformer using a primary coil lottery connection that mounts a contact point and a switching unit to change the supply current of the primary coil lottery according to the amount of power detected by the secondary coil to prevent power loss even under no load.

In general, a transformer is a device that modulates a voltage by an electromagnetic induction action without having a continuous moving part. The electromotive force of a transformer refers to electric power generated by the stopping of a conductor and the change of magnetic flux chain by time.

Conventional energy-saving transformers are designed to control the main power supply by configuring additional circuits through a separate small power supply device in addition to the primary coil to cut off the primary input voltage. There is a problem that can not be simply and turn off when not using electricity or turn on the power when using electricity, when the power is always consumed, there is a problem that can not effectively respond to the power consumption.

In addition, conventional transformers are mostly single-wire primary coils, and most technologies for saving power are very expensive because they control current according to the load of the output by inverter switching. In the case of a transformer, there is a method of driving and shutting off 1KW by using an additional required driving transformer for driving.

This method operates by simply using the secondary power and shuts down the main power when not in use. It can be used with a certain capacity regardless of various loads, and it is difficult to cope with load changes. .

For example, it is designed to use a small power supply to detect the signal of the remote control by operating and cutting off the power by the remote control. It is effective for driving only audio, radio, and TV, but it is mixed with audio, refrigerator, and light. For the use of a power source whose capacity changes due to the use of electric appliances, multi-stage capacity change is required in response to power consumption.

Conventionally, constant power is supplied, but the supply power cannot be efficiently controlled according to the load, so that constant power is supplied to the primary coil regardless of the load of the secondary coil, so that the fixed consumption lost by the primary coil without a load There is a problem that can not save and cut off the power.

The present invention has been made to solve the problems described above, by classifying the amount of current flowing in the primary coil into a multi-line lottery to detect the load consumed by the secondary coil with a Hall sensor to determine the load of the secondary coil. According to the present invention, a power saving type automatic transformer device and method by primary coil lottery connection which minimizes the fixed power consumption of the primary coil by controlling the amount of current flowing through the primary coil by controlling the multi-step by the microprocessor and operating the contact and the switching unit The purpose.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is to winding the primary coil in a four-wire lottery to divide the input into four to minimize the fixed power consumption of the primary coil, the configuration is the contact and switching unit 1, solenoid coil (2) ), The coil and the hall sensor unit 3, the current detection sensor and the signal conversion unit (4).

The contact and switching unit 1 connects or cuts off the coil of the lottery according to the input signal and is divided into multiple stages to turn on and off the supply current terminal. The solenoid coil unit 2 includes a low current driver, a medium current driver, and a high current. It consists of a driving unit and transmits a signal to the contact and the switching unit 1 to drive, the coil and the Hall sensor unit 3 functions to detect the amount of current consumed in the secondary coil, the current detection sensor and the signal conversion unit ( 4) detects the amount of current detected by the coil and the hall sensor unit 3 and controls the supply current of the primary coil step by step according to the change in the amount of current.

First, the current flows by switching to L1 of the primary coil, so that the current flows in the secondary coil with the smallest load, and the maximum load that can be supplied by L1 to the secondary coil is detected by the coil and the hall sensor unit 3. When the current detection sensor and the signal conversion unit 4 recognizes the maximum load amount and transmits a driving signal for increasing the current amount of the primary coil to the solenoid coil unit 2 to L2, the solenoid coil unit 2 is inputted. The contact signal and the switching unit 1 are controlled by the drive signal to switch the current of the primary coil to L2 to increase the capacity of the supply current.

Further, when the current flowing from the secondary coil is switched by the supply current terminal to L2 and the maximum load that can be supplied is detected by the coil and the hall sensor unit 3, the current detection sensor and the signal conversion unit 4 determine the maximum load amount. Recognizing and transmitting the drive signal for converting the current amount of the primary coil to the solenoid coil unit 2 to the next step L3, the solenoid coil unit 2 controls the contact and the switching unit 1 by the input drive signal Switch the current in the primary coil to L3 to increase the supply current capacity.

On the other hand, if the current flowing from the secondary coil is detected by the coil and hall sensor unit 3 as the maximum load that can be supplied by switching the supply current terminal to L3, the current detection sensor and the signal conversion unit 4 is the maximum load amount Recognizing and transmitting the drive signal for converting the current amount of the primary coil to the solenoid coil unit 2 to the next step, L4, the solenoid coil unit 2 controls the contact and the switching unit 1 by the input drive signal Switch the current in the primary coil to L4 to increase the supply current capacity.

On the contrary, when the current flowing in the secondary coil is reduced from the maximum load that can be supplied by switching the supply current terminal to L4, and the amount of current supplied is not insufficient even when the primary coil is connected to L3, the coil and Detects the amount of current detected by the Hall sensor unit 3 in the current detection sensor and the signal conversion unit 4 and transmits a drive signal for converting the amount of current of the primary coil to the solenoid coil unit 2 in the reduction step L3, The solenoid coil unit 2 controls the contact point and the switching unit 1 with the input drive signal to switch the current of the primary coil to L3 to reduce the capacity of the supply current.

If the current flowing from the secondary coil is reduced from the maximum load that can be supplied by switching the supply current terminal to L3, and the current amount supplied even when the primary coil is connected to L2 is converted into a state in which there is no shortage, the coil and Detects the amount of current detected by the hall sensor unit 3 in the current detection sensor and the signal conversion unit 4 and transmits a drive signal for converting the amount of current of the primary coil to the solenoid coil unit 2 in the reduction step L2, The solenoid coil unit 2 controls the contact point and the switching unit 1 with the input drive signal to switch the current of the primary coil to L2 to reduce the capacity of the supply current.

In addition, when the current flowing from the secondary coil is reduced from the maximum load that can be supplied by switching the supply current terminal to L2 and the current amount supplied even when the primary coil is connected to L1 is converted into a state in which the coil and Detects the amount of current detected by the Hall sensor unit 3 in the current detection sensor and the signal conversion unit 4 and transmits a drive signal for converting the amount of current of the primary coil to the solenoid coil unit 2 in the reduction step L1, The solenoid coil unit 2 controls the contact point and the switching unit 1 by the input drive signal to switch the current of the primary coil to L1 to reduce the capacity of the supply current.

As described above, in order to prevent unnecessary consumption of current in the primary coil, the load amount used in the secondary coil is detected, and when the current used in the secondary coil increases, the current amount of the primary coil is gradually changed to L2, The current input to the secondary coil is increased by increasing L3 and L4, and the current amount of the primary coil is gradually reduced to L2, L3, L4 and input to the secondary coil even when the current used in the secondary coil decreases. It operates in such a way as to reduce the current, which increases or decreases the input of the primary coil in accordance with the load of the secondary coil. In this case, a device for converting signal transmission is required to prevent chattering by a contact point, and a malfunction of a variable step must be prevented.

The windings of the primary coil are divided into regular power consumption and emergency power consumption, and the power consumption in emergency is divided into multiple stages to make a lottery ticket so that the control amount and the flexibility of operation can be efficiently operated according to the load amount.

FIG. 2 shows a three-wire lottery winding of the input of the primary coil 20. The secondary coil can be converted into L1, L2, and L3 step by step according to the load amount in the secondary coil. When the load is small, it operates at L1 and when the load of the secondary coil increases, the supply current of the primary coil 20 is increased to L2 and L3. On the contrary, when the load of the secondary coil decreases, L3 and L2. In order to reduce the supply current of the primary coil 20 to L1, the supply current of the primary coil 20 is divided into three stages according to the load of the secondary coil.

FIG. 3 shows the input divided by winding the input of the primary coil 30 into a four-wire lottery, and when the load in the secondary coil increases, conversion to L1, L2, L3, L4 can be performed step by step. On the contrary, when the load of the secondary coil decreases, the input of the primary coil 30 is controlled by L4, L3, L2, and L1.

4 illustrates a power saving type automatic transformer for controlling the input of the primary coil by using the Hall sensor 42 and the microprocessor 43 using the transformer 40 wound in a 3-wire lottery. The microprocessor 43 controls the amount of current 41 and the adjustment of the contacts and the switching units 44 and 45, and the operation is as follows.

First, a supply current having a size of L1 flows through the transformer 40 wound by a 3-wire lottery, and current flows through the secondary coil 41 at the smallest load amount, and the load amount used by the secondary coil 41 increases, thereby increasing L1. When the maximum load that can be supplied by the hall sensor 42 is detected, the microprocessor 43 transmits a signal to the contacts and the switching units 44 and 45 to convert the amount of current of the transformer 40 into L2. And the switching units 44 and 45 switch to L2 to increase the capacity of the supply current.

In addition, when the load used in the secondary coil 41 increases and the maximum load that can be supplied by switching the supply current terminal to L2 is detected by the hall sensor 42, the microprocessor 43 moves to the L3 transformer 40. The supply current amount of the conversion signal is transmitted to the contact point and the switching section 44, 45, the contact point and the switching section 44, 45 connects the transformer 40 to L3 to increase the capacity of the supply current.

On the other hand, the load amount used in the secondary coil 41 is reduced from the maximum load that can be supplied by L3 and sensed by the Hall sensor 42, even if the supply current of the primary coil is connected to L2, the amount of current supplied is insufficient. When the state is not reached, the microprocessor 43 transmits a current amount conversion signal to the contacts and the switches 44 and 45, and the contacts and the switches 44 and 45 connect the transformer 40 to L2 to supply the supply current. Reduce the dose.

Similarly, the load consumed by the secondary coil 41 decreases from the maximum load that can be supplied by L2 and is detected by the hall sensor 42 so that the amount of current supplied is not insufficient even when the transformer 40 is connected to L1. When the state is reached, the microprocessor 43 transmits the current amount conversion signal of the transformer 40 to the contact point L1 and the switching parts 44 and 45, and the contact point and the switching part 44 and 45 transmits the transformer 40 to L1. By connecting to reduce the capacity of the supply current, the contact current and the switching unit by controlling the supply current of the primary coil by the Hall sensor 42 and the microprocessor 43 according to the current load amount used in the secondary coil 41 (44, 45) controls the current flowing through the transformer 40 wound in a three-wire lottery.

On the other hand, in order to prevent the unstable operation of the contacts and the switching units 44 and 45 when converting the capacity of the supply current, the current detection of the secondary coil 41 is spaced between the operation time and the non-operation time so that the frequent supply current Prevents malfunction due to conversion of

FIG. 5 shows a power saving type automatic transformer for controlling the primary coil using the Hall sensor 52 and the microprocessor 53 using the transformer 50 wound with a four-wire lottery.

The supply current of L1 size is flowing in the transformer 50 wound by the 4-wire lottery, so that the current flows in the secondary coil 51 at the smallest load amount, and then the load used in the secondary coil 51 increases, and When the maximum load that can be supplied is detected by the Hall sensor 52, the microprocessor 53 transmits a signal to the contacts and the switching units 54, 55, 56 to convert the current amount of the transformer 50 into L2. And the switching sections 54, 55, 56 switch to L2 to increase the capacity of the supply current.

In addition, when the load used in the secondary coil 51 increases and the maximum load that can be supplied by switching the supply current terminal to L2 is detected by the hall sensor 52, the microprocessor 53 enters the transformer 50 to L3. The supply current amount of the conversion signal is transmitted to the contact and the switching unit 54, 55, 56, the contact and the switching unit 54, 55, 56 is connected to the transformer 50 to L3 to increase the capacity of the supply current.

When the load used in the secondary coil 51 increases and the maximum load that can be supplied by switching the supply current terminal to L3 is detected by the hall sensor 52, the microprocessor 53 supplies the transformer 50 to L4. The current amount conversion signal is transmitted to the contacts and the switches 54, 55, 56, and the contacts and the switches 54, 55, 56 connect the transformer 50 to L4 to increase the capacity of the supply current.

On the contrary, the load used in the secondary coil 51 decreases at the maximum load that can be supplied by switching to L4 and is detected by the hall sensor 52 so that the supply current of the primary coil 50 is connected to L3. When the amount of current to be reached is not insufficient, the microprocessor 53 transmits a current amount conversion signal to the contacts and the switches 54, 55 and 56, and the contacts and the switches 54, 55 and 56 are converted to L3. 50) to reduce the supply current capacity.

Similarly, the load consumed by the secondary coil decreases at the maximum load that can be supplied by switching to L3, and is detected by the hall sensor 52 so that the amount of current supplied even when the transformer 50 is connected to L2 is not insufficient. As early as possible, the microprocessor 53 transmits the amount of current conversion signal of the transformer 50 to the L2 to the contacts and the switches 54, 55, 56, and the contacts and the switches 54, 55, 56 transmit the L50 to the L2. ) To reduce the supply current capacity.

The amount of current used in the secondary coil 51 decreases from the maximum load that can be supplied by switching to L2 and is detected by the hall sensor 52 so that the amount of current supplied even when the supply current of the primary coil 50 is connected to L1. When the deficiency is reached, the microprocessor 53 transmits a current amount conversion signal to the contacts and the switches 54, 55, 56, and the contacts and the switches 54, 55, 56 transmit L 50 to the transformer 50. Reduce the supply current capacity.

On the other hand, in order to prevent the unstable operation of the contacts and the switching sections 54, 55, 56 when converting the capacity of the supply current, the current detection of the secondary coil is spaced between the operation time and the non-operation time so that the frequent supply current Prevents malfunction due to conversion.

6 is a flowchart illustrating the operation of the automatic transformer as follows.

When power is supplied to the energy-saving autotransformer, the transformer supplying the input current is set to A and operates (steps S60 and S61). The Hall sensor detects an increase or decrease in the load amount of the secondary coil at regular intervals (steps S62 and S63), and the microprocessor transmits a signal for converting the supply current corresponding to the load amount of the secondary coil input from the hall sensor. (Step S64). The contact and the switching unit perform a switching conversion operation of increasing or decreasing the supply current in accordance with the signal input from the microprocessor to convert the transformer into B (steps S65 and S66). On the other hand, the transformer conversion step is divided into multiple stages according to the change of the load amount of the secondary coil, and is converted adaptively. The transformer is converted to B and fed back to step S62 to operate (step S67). The operation is terminated when the power supply of the automatic transformer is cut off (step S68).
