A power conversion device according to the present disclosure is applied with a DC input voltage and outputs a DC output voltage to a load. The power conversion device includes first to fourth switch elements, a resonance circuit including an inductor and a capacitor, a transformer in which the inductor, the capacitor, and a primary-side coil are connected in series, a rectifier circuit, a smoothing circuit, and a controller. The controller controls an operation frequency, simultaneously switches the first and fourth switch elements in a first mode, and switches the fourth switch element with a phase of the fourth switch element delayed by a predetermined first phase with respect to the first switch element in a second mode. The controller switches the first and second modes according to at least one of the output voltage, an output current, a dead time current, the input voltage, and a circuit temperature.
