High energy conversion strategy of SRM with single-pulse switching

This paper investigates an optimal switching angle of SRM (switched reluctance motor) drive system for maximum energy conversion ratio. A new magnetizing method is proposed with a low switching frequency to increase the energy conversion ratio that is related to the efficiency of the motor. The proposed algorithm enlarges the active energy conversion region, which is converted to mechanical output, and reduce the reactive power region with same field energy region. As results, a torque ripple is also sufficiently reduced compared with that of the conventional switching angle magnetizing approach. Some implementations show that proposed scheme is a valuable approach to have a high efficiency and low ripple drive of an SRM.
