Abstract: PURPOSE: A battery supply circuit is provided to compulsorily close an operation of an interleave power factor correction circuit by sensing the generation of an abnormal current of the interleave power factor correction circuit. CONSTITUTION: A rectifier(20) rectifies voltage of a power source. A power factor correction circuit(30) comprises a plurality of reactors, a plurality of switches, and a plurality of current detectors. The plurality of reactors stores a rectified current. The plurality of current detectors outputs voltage according to the current outputted from the reactor. A power factor correction circuit controller(40) controls power factor correction operation by adjusting the switching of the switch. A power factor correction circuit protection unit(70) stops an operation of the power factor correction circuit controller.
