Abstract: A power conversion apparatus according to one aspect of the present disclosure comprises a bridge circuit including a first switch and a second switch, a first auxiliary switch, a first auxiliary inductor, a control device, a transformer, a secondary-side inductor, a rectifier circuit, a smoothing circuit, and an output detection circuit. The control device performs an on/off operation on the first auxiliary switch if a value detected by the output detection circuit is smaller than or equal to a setting value, and maintains the first auxiliary switch in an off state if the detected value exceeds the setting value.
