Abstract
A transient current in a rectifier circuit is efficiently reduced. In a rectifier circuit, a first rectifier is provided between the first terminal and a second terminal. In the rectifier circuit, when a switch element is turned ON, a primary winding current flows from a power source to a primary winding in a transformer. When the switch element is turned OFF, a second rectifier current flows from a secondary winding in the transformer to a second rectifier. When the second rectifier current flows, a first reverse voltage is applied between the first terminal and the second terminal. The first reverse voltage is a reverse voltage applied instantaneously.
