摘要：
A novel active snubber soft-switched method is proposed to achieve zero-voltage and zero-current switching (ZV-ZCS) for pulsewidth modulation (PWM) dc-dc 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, Some other basic PWM dc-dc topologies with the proposed snubber are also been given.
