发明名称 POWER SUPPLY FOR PREVENTING A POWER ELEMENT FROM BEING BROKEN DUE TO A SHORT CIRCUIT
摘要 A power supply for preventing a power device from being damaged due to a short circuit is provided to inform a user of a trouble inside by self-diagnosing the insulating performance of the insulating member. A power supply unit is grounded in a first ground terminal, includes a first power device, and outputs a first DC power by receiving an AC power. An inverter(140) is commonly grounded in the first ground terminal and outputs a driving power source by receiving the first DC power. A heat sink(150) is connected to a second ground terminal insulated from the first ground terminal and discharges the heat of the first and second power devices. An insulating member(160) is interposed between the heat sink and one of the first and second power devices. A microcomputer(170) determines the performance of the insulating member based on the current value flowing between the heat sink and the first ground terminal.
