Abstract :
A hybrid phase modulated converter with current doubler rectification has been analyzed. The operating principles in continuous conduction mode are discussed. Various equations and equivalent circuits that aid in design have been derived. How this topology compares against a conventional hybrid resonant converter has been delineated under various design considerations. The zero voltage switching characteristics, filter requirements, small-signal transfer characteristics, device ratings and magnetics size requirement are discussed. Simulation results and experimental verification from a 500 W prototype converter switched at 100 kHz are presented.
