Abstract
In this DC/DC converter, a first switching circuit is connected between a first winding of a transformer and a DC power supply, and a second switching circuit is connected between a second winding and a battery. A control circuit includes a first circuit for performing feedback control so as to reduce a difference between a detected value and a command value of charge current, and a second circuit for correcting one of control input and output of the first circuit on the basis of the detected value and the command value. In charging the battery, the control circuit controls a phase shift amount of a first diagonal element in the first switching circuit and a phase shift amount of a second diagonal element in the second switching circuit relative to the drive phase of a first reference element in the first switching circuit.
