POWER SUPPLY APPARATUS

摘要

The present invention relates to a power supply apparatus, and more specifically, to a power supply apparatus which can supply power to an output part stably regardless of a problem in a power source of a comparator as solving a problem of an entering current. The power supply apparatus according to an embodiment of the present invention includes: a power supply part which is connected between an input part and an output part, and includes a plurality of capacitors charged by an input power source inputted from the input part sequentially, and outputs a first control signal if each capacitor is charged with a reference voltage; a first output control switch which is connected between the power supply part and the output part; a second output control switch which is connected between the input part and the output part; and a control part which turns on all of the first output control switch and the second output control switch if the first control signal is outputted. The second output control switch may be a latch relay.
