Abstract :
A power factor correction (PFC) based bridgeless Sheppard-Taylor converter for feeding brushless DC (BLDC) motor dive is presented in this work. The voltage of DC bus of the voltage source inverter (VSI) feeding BLDC motor is adjusted for speed control. The BLDC motor is electronically commutated to operate the VSI in low switching frequency for reducing the switching losses in it. The proposed PFC converter is operated in discontinuous inductor current mode (DICM) for inherent power factor correction using a single voltage sensor. The performance of the proposed PFC converter feeding BLDC motor drive is evaluated for control of speed over a wide range. A unity power factor is achieved with power quality indices acceptable within the limits of IEC 61000-3-2.
