Current doubler rectifier (CDR) is one of the best candidates for high output current DC-DC converters. In this paper, several conventional CDR snubber circuits are evaluated, and two passive lossless snubber circuits for the CDR are proposed to reduce the reverse-recovery-related losses and clamp the voltage spikes across the rectifiers. The snubber circuits are tested and verified experimentally, and higher efficiency is achieved when compared to the conventional resistive snubbers.
