The present invention provides a converter that comprises: two transformers in which a first winding is connected to a primary side and a second winding and a third winding are connected to a secondary side; a full-bridge inverter in which four switches positioned in a first leg and a second leg are driven in a full-bridge form, and the first transformer is positioned between the first leg and the second leg; an LLC resonance circuit in which two switches positioned in the second leg are driven in a half-bridge form, and a resonance inductor, a resonance capacitor, and the second transformer are connected in series; and an output stage rectifier circuit which includes an LLC rectifier circuit rectifying power transmitted to the secondary side by the LLC resonance circuit, and includes a first diode connected to the second windings of two transformers in series, a second diode connected to the third windings of two transformers in series, and a third auxiliary diode transmitting the output of the LLC rectifier circuit toward a load.
