Abstract
A DC-DC converter includes a first full-bridge circuit and a second full-bridge circuit isolated by a transformer. The first full-bridge circuit includes switching elements, a first floating capacitor, and a second floating capacitor. The first full-bridge circuit operates in at least one of a full-bridge operation mode and a half-bridge operation mode. In switching of the operation mode, switching phases of the first full-bridge circuit are shifted in two portions in one cycle of a drive frequency, and shift amounts of the phases are determined such that positive and negative output voltages of the first full bridge circuit are balanced before and after the operation mode is switched.
