<p>Disclosed is a resonant converter. The resonant converter includes a switching unit, an LC resonance circuit unit, a transformer, and a rectifying unit. The switching unit includes a plurality of switches S1 to S4 converting a DC voltage into an AC voltage by alternate switching. The LC resonance circuit unit is connected to the switching unit to convert frequency characteristics of the AC voltage delivered from the switching unit using a resonance phenomenon of a resonance inductor and a resonance capacitor. The transformer includes a primary winding connected to the LC resonance circuit unit and a secondary winding with a certain turns ratio with respect to the primary winding. The rectifying unit includes a plurality of rectifier diodes for rectifying an AC voltage induced at a secondary side of the transformer into a DC voltage. Here, the rectifying unit including the plurality of rectifier diodes connected in series includes capacitors disposed at both ends of each rectifier diode to improve a waveform of a resonant current and balance voltages between the rectifier diodes.
