Abstract
The power conversion device includes a converter including a main switch element, a main rectifying element, an output capacitor, and a primary winding of a coupled inductor and a resonance assist circuit based on a closed-loop circuit including a first series circuit having a secondary winding of the coupled inductor, a first rectifying element, and an auxiliary switch element, a second series circuit having a tertiary winding of the coupled inductor and a second rectifying element, and an auxiliary capacitor to which the first series circuit and the second series circuit are connected. The secondary winding and the tertiary winding are separate bodies and the first series circuit and the second series circuit are connected in parallel to the auxiliary capacitor, or the tertiary winding is integrated with the secondary winding.
