Abstract: A power supply apparatus of a home appliance which meets standby power regulation of 0.5 watts using one SMPS. As compared with a general circuit which meets the standby power regulation using two or more SMPSs, it may be possible to curtail expenses required for addition of a separate standby only SMPS and miniaturize a PCB, resulting in a reduction in cost. Further, in a washing machine employing a motor, a circuit is provided to bypass a back EMF generated in the motor even if AC power is not supplied to the washing machine due to occurrence of a power failure or unplugging of the washing machine. Therefore, it may be possible to prevent a PCBA from being damaged due to the back EMF.

Abstract translation: 一种家用电器的电源设备，使用一个SMPS满足0.5瓦的待机功率调节。 与使用两个或更多SMPS的备用功率调节的通用电路相比，可以减少添加单独的仅备用SMPS所需的费用并且使PCB小型化，从而降低成本。 此外，在采用电动机的洗衣机中，即使由于电源故障的发生或洗衣机的拔出而没有向洗衣机供给交流电力，也设置有绕过电动机中产生的反电动势的电路。 因此，可以防止PCBA由于反电动势而被损坏。
