Title:
STANDBY POWER SAVING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2015/119382
Kind Code:
A1
Abstract:
In the present invention, a switching element is disposed between an SMPS, which supplies a power to a load side, and a power unit, which supplies a power to the SMPS, so that the power supply to the SMPS is interrupted by turning off the switching element in a standby mode while the power is supplied to the SMPS only when an electronic device is operated. Therefore, the present invention can reduce the standby power. Further, in the present invention, a circuit for supplying power to a load and a circuit for providing a standby power are separated, and a power storage unit for supplying a driving power to the switching element is disposed within the circuit for providing the standby power. Further, when a charged power of the power storage unit becomes lower than a reference value, power is supplied to only the circuit for providing the standby power to charge the power storage unit, thereby minimizing the standby power consumption.
