Abstract :
A ZCS PWM switch circuit for the interleaved boost converters is proposed in this paper. Only one auxiliary switch is used in the active soft switching circuit. By using this ZCS converter topology, zero current turn-on and zero current turn-off of the main switches can be achieved and the reverse-recovery loss of boost diode can be reduced. In addition, the auxiliary switches are ZCS during the turn-on and turn-off switching transition. A prototype of boost converter rated at 500W has been built to confirm the effectiveness of the converter.
