In this paper, the authors deal with a novel controller viz. fuzzy logic controller to drive a voltage controlled PMBLDCM drive for better performance and efficiency. Here a buck half-bridge DC-DC converter was 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 PMBLDCM is used to drive a compressor load of an air conditioner through a three-phase VSI fed from a controlled DC link voltage.
