    摘要: A switching mode power supply (SMPS) includes a rectifier to rectify an alternating current (AC) voltage; a first transformer to convert the rectified voltage into a first output voltage of the SMPS according to a switching operation of a first switching unit; a second transformer to convert the rectified voltage into a second output voltage of the SMPS according to a switching operation of a second switching unit; first and second switching control units to control the switching operations of the first and second switching units; a power blocking unit to block power supply according to a light signal. The power blocking unit is electrically insulated from the light emitting unit.
