• zero-voltage switching

A switching control strategy is proposed for single- and dual-inductor current-fed push-pull converters. The proposed switching control strategy can be used with both current-fed push-pull converters with an active voltage doubler rectifier, or active rectifier, in the secondary-side of the isolation transformer. The proposed switching control strategy makes turn-on and turn-off processes of the primary-side power switches zero-voltage switching and zero-current switching, respectively. The soft-switching operation of the single-and dual-inductor push-pull converters, with both types of active rectifier, is explained. Simulation and experimental results are provided to validate soft-switching operation of the current-fed push-pull converters with the proposed switching control strategy.
