Abstract

A first rectification circuit includes a bypass element connected to both ends of a rectification element. The bypass element is smaller in voltage drop amount than the rectification element. A power supply device is configured to perform switching between a first mode and a second mode based on at least one of information showing a magnitude of electric power that is being supplied to a load and information showing a magnitude of electric power that is to be supplied to the load. In the first mode, an AC voltage is rectified in a path including the rectification element. In the second mode, the AC voltage is rectified in a path including the bypass element.
