Abstract	A novel snubber circuit for high-frequency PWM (pulse width modulations) DC-to-DC and DC-to-AC converters is presented. The snubber is a series circuit of a capacitor and a snubber switch which is connected across the main switch. The main switch and the snubber switch are switched alternately with a short dead time. The condition of zero-voltage switching is satisfied both in the main switch and the snubber switch by applying the switched snubber. The turn-off surge due to parasitic inductance in the circuit and the recovery of the diode are eliminated by the switched snubber without increasing the voltage stress and the conduction losses in the main switch.
