Abstract
A power converter apparatus includes a primary bridge having a plurality of diagonally opposed primary power elements, and a secondary bridge having a plurality of diagonally opposed secondary power elements. The primary and secondary bridges are electrically coupled by a transformer. At least one control unit is configured to phase-shift switch the primary and secondary power elements, such that one or more of the primary and secondary power elements are switched off under near-zero current conditions to reduce voltage and current stresses and commutation losses within the power converter.
