Abstract
A power converter includes a transformer including a transformer including a primary winding and a secondary winding magnetically coupled to the primary winding, a bridge circuit including a switching element, and an inductor. A direct current voltage is converted into an alternating current voltage by turning on and off the switching element in the bridge circuit. An output voltage in the secondary winding is induced by supplying the alternating current voltage to the primary winding. The inductor is disposed on a path connecting the switching element and the primary winding. A resonance inductance value Lr including a leakage inductance value of the transformer and an inductance value of the inductor satisfies Formula 1.
