Abstract

The present invention aims to provide a power converter, which includes a plurality of switching power supply devices connected in parallel, with a circuit configuration that enables reduction of cost and a size of the power converter. The present invention relates to a power converter including at least a first switching power supply device and a second switching power supply device connected in parallel. A part of high-voltage-compatible switching elements is commonly used between the first switching power supply device and the second switching power supply device, and a drive gate signal of one of the high-voltage-compatible switching elements of the first switching power supply device and the second switching power supply device and a phase difference of a drive gate signal of the commonly used switching power supply device are set to be equal when a load current is a first current value or lower.
