Abstract :
In this paper, the authors propose an advanced brushless DC motor (BLDCM) drive for low cost and high performance electric propulsion system in electric vehicles (EVs) and hybrid electric vehicles (HEVs). It includes reduced parts power converter topologies and an optimal PWM control strategy to produce the desired dynamic and static speed and torque characteristics. The theoretical explanation and operational principle are described in detail, and the performance of the proposed low cost BLDCM drive is compared with its conventional counterpart by informative simulation results. An IGBT inverter with high speed DSP (TI TMS320 F243) is also built to provide experimental results
