Abstract
A power supply circuit to detect whether or not abnormal current is generated in a power factor compensation circuit and forcibly stop an operation of an interleaved power factor compensation circuit controller if abnormal current is generated. The power supply circuit includes a rectifier, a power factor compensation circuit including a plurality of reactors, a plurality of switches and a plurality of current detectors, a power factor compensation circuit controller to control switching of the switches and to control a power factor compensation operation, and a power factor compensation circuit protection circuit to receive the voltages output from the plurality of current detectors and to stop the operation of the power factor compensation circuit controller if at least one of the voltages output from the plurality of current detectors is abnormal. Thus, it is possible to prevent failure of the switches and the current detectors due to abnormal current.
