Abstract

This paper aims at a power factor corrected (PFC) buck bridge DC-DC converter for a permanent magnet brushless DC motor (PMBLDCM) for an air conditioner. This PFC converter is fed from a single-phase AC mains through a diode bridge rectifier (DBR) and connected to a voltage source inverter (VSI) feeding the PMBLDCM. The Speed of the proposed PMBLDCM drive is controlled to improve efficiency of the air conditioning system. The control scheme for the PFC bridge converter based PMBLDCM drive is designed, modeled and its simulation is carried out in Matlab-Simulink environment for an air conditioner compressor driven through a 3.75 kW, 1500 rpm PMBLDC motor. The obtained results are presented to validate the effectiveness of the proposed PFC converter based adjustable speed drive. An improved power quality is observed with almost unity power factor and improved efficiency of the drive in a wide range of the speed and an AC input voltage.
