Apparatus and Method for Supplying Stand-by Electric Power Using Super-capacitor}

The present invention relates to a standby power supply apparatus and method using a super-capacitor, and more particularly to standby power using a super-capacitor in an electric and electronic device capable of remote control using a remote controller. A standby power supply and method for saving energy are provided.

In general, electric and electronic devices such as TVs, fans, air conditioners, and audio used in places such as homes and offices are provided with remote controllers for the convenience of users, thereby enabling remote control by users.

The remote control by the remote control, and receives the remote control signal transmitted from the remote control through the remote control receiver provided in the electrical and electronic equipment to the control unit, and the control unit determines the remote control signal transmitted through the remote control receiver to correspond to this By controlling the electrical and electronic equipment to perform the control operation.

Typically, the electronic and electronic devices that can be controlled by the remote controller should provide a minimum power to the controller including the remote controller receiver even when the operation is stopped. This is to receive a remote control signal transmitted from the remote control when the user controls the electronic device is stopped operation to perform a function corresponding thereto.

As such, in order to perform a remote control operation of the electronic device by the remote control, for example, a constant power supply, that is, standby power, must always be supplied to the electronic device through a plug connected to an outlet. It must be equipped with a standby power supply for supplying power.

As shown in FIG. 1, a general standby power supply device includes a main power supply unit 110, a remote control reception power supply unit 120, a remote control receiver 130, and a controller 140.

The main power supply unit 110 receives commercial power at all times and converts it into main power required for the operation of the electric and electronic device, and provides the same to each component under the control of the controller 140.

As described above, the standby power supply device must provide standby power to always maintain the standby state so that even when the electrical and electronic equipment is not in operation, the remote control signal can be received from the remote controller to perform a corresponding function. There is a problem that the commercial power is continuously supplied to the electrical and electronic equipment through the plug connected to the outlet, causing power loss.

According to the data of the Korea Electrotechnology Research Institute, in the case of a typical TV, standby power consumption is 4.33 (W) per hour, and standby power consumption is 24 * 4.33 = 103.92 (W) per day. At 1.11 (W) per day, the standby power consumption per day is 24 * 1.11 = 26.751 (W).

As such, even when the electrical and electronic equipment is not operating, the standby power is consumed by several tens of watts per hour according to statistics, and when it is converted nationwide, hundreds of millions of watts are unnecessarily wasted. will be.

In addition, in order to reduce such unnecessary waste of power, when the standby power is maintained at zero watts by shutting off commercial power supplied to the electrical and electronic devices, the remote control cannot control the corresponding electrical and electronic devices. Therefore, in order to control the remote control, the user must directly operate the switch of the main power supply unit provided in the electrical and electronic device to apply commercial power to the electrical and electronic device to drive the electrical and electronic device, and then control the electrical and electronic device with the remote control. There is discomfort.

2 is a block diagram showing the configuration of a standby power supply using a super-capacitor according to an embodiment of the present invention.

Standby power supply apparatus using a super-capacitor according to an embodiment of the present invention, as shown in Figure 2, the switch unit 210, the main power supply unit 220, the super-capacitor 230, the remote control receiver 240 ), And a control unit 250.

The switch unit 210 may use, for example, a relay, a silicon controlled rectifier (SCR), a triac (triode AC switch), or the like, and may be switched on or off under the control of the controller 250. The commercial power (for example, 330V, 220V, etc.) is switched or cut off to the main power supply 220. That is, the switch unit 210 is switched on according to the switching on control signal applied from the control unit 250 to switch commercial power to the main power supply unit 220, and also according to the switching off control signal applied from the control unit 250. Switching off to cut off the commercial power is switched to the main power supply 220.

The main power supply unit 220 receives commercial power through the switch unit 210 by switching on the switch unit 210, and operates the applied commercial power under the control of the control unit 250 to operate the electric / electronic device. It is then converted into mains power for remote control operation and provided to each component.

The super-capacitor 230 uses, for example, a P-EDLC, and receives the main power from the main power supply 220 under the control of the controller 250 (ie, the controller 250 in the standby state). After charging with the power required for the remote control of the control unit and provides to the remote control receiver 240 and the controller 250. That is, the super-capacitor 230 receives the main power from the main power supply unit 220 under the preset reference value under the control of the controller 250 and receives the corresponding power until the charge capacity becomes full. After the main power is charged, the charged power is supplied to the remote controller receiver 240 and the controller 250 under the control of the controller 250.

Here, it should be understood that a high capacity capacitor, a rechargeable battery, or the like may be used instead of the super-capacitor 230. In addition, the reference value in the standby state of the electrical and electronic device, the control unit 250 detects the amount of power charged in the super-capacitor 230, and generates a switching on control signal and a switching off control signal to switch unit 210 ) To perform the switching on operation and the switching off operation of the switch unit 210, and to supply the minimum power required to perform a control operation such as receiving a remote control signal from the remote controller through the remote control receiver 240. The value set in advance through a test or the like (ie, the amount of power required for the control unit 250 to perform a control operation in a standby state (that is, a state in which commercial power is cut off)).

The remote control receiver 240 performs an operation by using the power provided from the main power supply 220 or the super-capacitor 230 under the control of the controller 250, and receives the remote control signal transmitted from the remote controller. 250).

The controller 250 controls the overall operation of the electrical and electronic device. In particular, the controller 250 determines a remote control signal transmitted from the remote controller receiver 240 and performs a control operation corresponding thereto. In addition, when the standby state of the electrical and electronic device, the control unit 250 receives a power charged in the super-capacitor 230 to perform a control operation (ie, a remote control operation) of the electrical and electronic device, -Detects the amount of power charged in the capacitor 230 and controls the switching on / off operation of the switch unit 210 according to the detected charge capacity.

In other words, the controller 250 checks whether the charging capacity of the super-capacitor 230 is full when the switch unit 210 is switched on in the standby state of the electrical and electronic device. A switching off control signal is generated and applied to the switch unit 210. In addition, the controller 250 compares whether or not the charging capacity of the super-capacitor 230 is less than or equal to a preset reference value in the switching off state of the switch unit 210 in the standby state of the electrical and electronic device, In this case, a switching-on control signal is generated and applied to the switch unit 210.

Hereinafter, a method of supplying standby power using a super-capacitor according to an embodiment of the present invention will be described in detail with reference to the flowchart of FIG. 3.

First, in the standby state of the electrical and electronic device, the control unit 250 receives the power charged in the super-capacitor 230 to perform a control operation, and at this time, the super-capacitor 230 is applied to the super-capacitor 230 at a predetermined time interval. After detecting the amount of charged power (S301), it is compared whether or not the charging capacity of the super-capacitor 230 is less than a predetermined reference value (S302).

Alternatively, the controller 250 may receive the power supplied from the super-capacitor 230 when receiving the power charged in the super-capacitor 230 when an event such as a remote control operation occurs without performing the above-described step S301. You can also compare directly below this threshold.

At this time, when the charge capacity of the super-capacitor 230 is less than the reference value in step S302 described above, the controller 250 determines whether the state of the switch unit 210 is off, that is, whether the switch unit 210 is currently switched off. Check (S303).

If the switch unit 210 is in the switching-off state in step S303 described above, the control unit 250 generates a switching on control signal for switching on the switch unit 210 and applies it to the switch unit 210. By performing the switching on control operation (S304).

Accordingly, the switch unit 210 performs a switching-on operation according to the switching-on control signal applied from the control unit 250 to switch commercial power to the main power supply unit 220, and the main power supply unit 220 switches the switch unit 210. By switching on the commercial power applied through the switch unit 210 is converted into a power that can be charged in the super-capacitor 230 is applied to the super-capacitor 230 to be charged (S305).

On the other hand, when the switch unit 210 is not in the switching off state in the above-described step S303, the control unit 250 is the case that the state of the switch unit 210 is on, that is, the switch unit 210 is currently in the switching on state As such, the charging operation to the super-capacitor 230 is continuously performed as in step S305 described above.

After performing the operation of step S305 described above, the controller 250 checks whether the charging capacity of the super-capacitor 230 is full at a predetermined time period (S306).

Alternatively, the controller 250 does not check at a predetermined time period, and when the power is charged in the super-capacitor 230 when an event such as a remote control operation occurs, the control unit 250 receives the power supplied from the super-capacitor 230. You can also directly compare whether sheep are full.

At this time, if the charge capacity of the super-capacitor 230 is not full at step S306 described above, the control unit 250 returns to step S305 described above to continue the charging operation to the super-capacitor 230. .

On the other hand, when the charge capacity of the super-capacitor 230 is full in the above-described step S306, the controller 250 generates a switching off control signal for switching off the switch unit 210 to switch unit 210. ) To perform the switching off control operation (S307).

Accordingly, the switch unit 210 cuts off the commercial power switched to the main power supply unit 220 by performing a switching off operation according to the switching off control signal applied from the control unit 250 (S308).

On the other hand, if the charge capacity of the super-capacitor 230 is greater than the reference value in step S302 described above, the controller 250 checks whether the charge capacity of the super-capacitor 230 is full at a predetermined time period (S309). .

Alternatively, the controller 250 does not check at a predetermined time period, and when the power is charged in the super-capacitor 230 when an event such as a remote control operation occurs, the control unit 250 receives the power supplied from the super-capacitor 230. You can also directly compare whether sheep are full.

If the charging capacity of the super-capacitor 230 is not full at step S309 described above, the process returns to step S301 described above to repeat the above-described operation.

On the other hand, if the charging capacity of the super-capacitor 230 is full in the above-described step S309, the controller 250 checks whether the switch unit 210 is currently switched on (S310).

In this case, when the switch unit 210 is not in the switched on state in the above-described step S310, the control unit 250 returns to the above-described step S301 when the switch unit 210 is currently switched off. Repeat it.

When the switch unit 210 is switched on in the step S310 described above, the control unit 250 returns to the step S307 described above and performs a switching off control operation to switch to the main power supply 220. Shut off commercial power.

When the standby power supply method using the super-capacitor according to the embodiment of the present invention as described above is applied to a general TV, the super-capacitor 230 is changed from a preset reference value to a full state in the standby state of the electrical and electronic device. The time required to charge one time is about 3 minutes, the amount of power consumed at the time of one charge is about 0.024 (W), and the time it takes for the super-capacitor 230 to discharge once from the full state to the preset reference value is about 5.42. (hr) about 24 / 5.42 = 4.42 times a day. Accordingly, the standby power consumption in the standby state of the electrical and electronic devices is 0.024 * 4.42 = 0.10608 (W), it can be seen that the standby power amount is significantly reduced compared to the existing technology. At this time, the super-capacitor 230 is used when 2.3V / 22F 2 series.

In the above-described embodiment of the present invention, in an electric electronic device remotely controlled by a remote controller, the electric power is charged to the super-capacitor by receiving commercial power when performing the normal operation of the electric electronic device. In the case of switching, the super power to reduce the amount of standby power of the electric and electronic devices by supplying the power charged to the super-capacitor to the standby power to cut off the commercial power supplied to the electric and electronic devices and to maintain the standby state.
