Power Factor Improvement of BLDC Motor Drive using Boost PFC Converter

This paper presents brushless dc (BLDC) motor drive with boost power factor correction to overcome power quality problem at AC mains. Boost PFC converter is applied to achieve unity power factor at AC mains. A reduction in harmonics is also observed. Here we are analyzing a conventional BLDC motor drive and comparing with Boost PFC based BLDC motor drive and expected improvement in overall power factor is seen. In this paper we simulate two cases of BLDC motor drive with and without PFC converter using Matlab/Simulink.
