Abstract


In this paper, a half-bridge DC-DC converter is used as a single-stage power factor correction (PFC) converter for feeding a voltage source inverter (VSI) based permanent magnet brushless DC motor (PMBLDCM) drive. The front end of this PFC converter is a diode bridge rectifier (DBR) fed from single-phase AC mains. The Vienna Rectifier PFC converter is operated with the current multiplier control and voltage follower control schemes for improvement of power quality (PQ) at ac mains while controlling the operation of PMBLDCMD in wide range of speeds and input AC voltage variation.
