Abstract
An isolated DC-DC converter includes a transformer, a full-bridge switching circuit, a protective circuit, a control unit, an inductor, and an output circuit. The isolated DC-DC converter includes a first voltage detection unit that detects a voltage value between a first conductive path and a second conductive path, and a first current detection unit that detects a current value of the inductor. The control unit determines at least one of a first dead time and a second dead time on the basis of the voltage value detected by the first voltage detection unit and the current value detected by the first current detection unit, using a method that increases the dead time as the voltage value increases and reduces the dead time as the current value increases.
