ABSTRACT
In this work a bridgeless PFC boost rectifier is proposed to reduce harmonic current of a BLDC motor. The aim of the work is to improve the input power factor of PMBLDC drive. Conventional bridged PFC topology is replaced by bridgeless PFC topology. Conventional VSI fed BLDC motor suffers from the high conduction loss in the input rectifier-bridge. Higher efficiency can be achieved by using the bridgeless boost topology. Performance comparison between the VSI fed BLDC motors with filters and the bridgeless boost rectifier fed BLDC motor are presented. The simulation results with bridgeless boost converter show that there is an improvement in power factor. The hardware is fabricated and tested. Simulation and experimental results of these systems are presented and the performance measures are compared. Experimental measurements agree acceptably with simulation results, and validate the proposed methods.
