An improved inductance-voltage clamping full-bridge soft-switch circuit including a full-bridge converter, a transformer, an output rectifying unit, an inductor, a clamping resistor, a capacitor, a first clamping diode, and a second clamping diode. The inductor includes a first winding used as an auxiliary inductor and a second winding used for clamping. A capacitor is connected in parallel with the clamping resistor connected in series.
