Abstract

A simple soft-switched switched reluctance motor (SRM) drive circuit was proposed, involving only three transistors. The circuit aims to drive the SRM with low EMI and with higher efficiency. The circuit performs soft switching by a simple switching method just like the usual hard switching drives. The current cut-off action of the motor windings can be done in a resonant way, so that the current in the windings rapidly researches zero, and the maximum output torque increases by means of short current pulse tail-length
