Abstract
A method for controlling a power conversion device for converting power from a power supply by controlling an input to a resonance circuit comprising a resonance coil and a resonance capacitor, with a switching element, the method comprising simultaneously changing a switching frequency and a time ratio of the switching element so that the switching element satisfies a condition of zero-voltage switching when an output power of the power conversion device is changed.
