A novel active snubber soft switched method is proposed to achieve zero-voltage and zero-current switching (ZV-ZCS) for PWM DC-DC power converters. The unique location of the snubber capacitor and inductor ensures low current stress and commutation losses in the auxiliary circuit. A boost converter adopting this technique is presented as an example, to illuminate its operation principles and derive the design procedures. Simulation and hardware implementation of a 350 W, 150 kHz boost converter have been made to validate the operation and the efficiency improvement compared to its hard-switching counterpart. Some other basic PWM DC-DC topologies applied with proposed snubber have also been given.
