Abstract

A pulse width modulation resonance converter is provided that includes a transformer and a switching unit including first to fourth switches electrically connected to a primary coil of the transformer and configured to convert a DC voltage into an AC voltage by a switching operation of the first to fourth switches in which each switch is switched from an off state to an on state when a voltage difference between both ends is about 0. Additionally, a rectifying unit includes an output capacitor, first to fourth diodes electrically connected to a secondary coil of the transformer, and a resonance tank having a resonance capacitor and a resonance inductor which are electrically connected to the secondary coil of the transformer. The plurality of switches connected to the primary side of the transformer perform the zero-voltage switching using the magnetized inductance of the primary side to minimize the switching loss.
