Abstract :
A high efficiency parallel post regulator for wide range input dc-dc converter is proposed. It achieves ZVS in the primary side switches in full range load due to operation; it also reduces voltage stresses across main rectifiers and has smaller conduction losses compared with the conventional post regulators; furthermore the requirement of input and output filters are significantly reduced due to the perfect filtered waveforms. A 250-400 Vdc 12 V/40 A prototype has been built and detailed experimental results are given to verify the theoretic analysis.
