In this paper a power factor correction (PFC) based Hybrid Resonance Pulse Width Modulation (HRPWM) fed brushless DC motor (BLDC) drive is proposed, analyzed and tested. In this regard, small signal and circuit analysis of HRPWM are calculated in resonance frequency, above-and below-resonance frequency. The control method for regulating DC link voltage is also presented. Furthermore, speed of BLDC motor is controlled by VSI duty cycle variations. Simulation results depict unit power factor, low THD and appropriate speed control.
