Abstract :
A new prototype of a secondary-side phase shifted (SPS) zero voltage and zero current soft switching PWM dc-dc converter with active rectifier is presented in this paper. The proposed dc-dc converter has no circulating current in the full-bridge circuits both of the primary and secondary sides, so that the related idling power can be minimized. Beside that, a wide-range soft switching can be attained from full load to no load by utilizing parasitic inductances of the high frequency (HF) transformer. The essential performance of a 1kW-50kHz prototype of the proposed dc-dc converter is originally demonstrated in experiments, and its effectiveness is discussed from the practical point of view.
