ABSTRACT:
Apparatus, methods, system and devices for providing a high efficiency parallel post regulator for a wide range input DC/DC converter. The wide input range DC/DC converter achieves zero-voltage-switching in the primary side switches in full range load due to 0.5 duty cycle of the operation at full load. The DC/DC converter reduces voltage stresses across main rectifiers, has a smaller conduction losses compared with conventional post regulators and the requirement of input and output filters is significantly reduced due to the filtered waveforms produced.
