Abstract

A resonant pulse soft-switched drivecircuit for a switchedreluctancemotor is proposed. There are nines witching devicesin the circuit with three phase motor windings, three devices for main circuit, three devices for auxiliary circuit, and three devices for charging circuit. Auxiliary thyristor is used so resonance currentpulse tail-length is fast cut off. Transformeris used so that the excessive energy is restored to the source and voltage of capacit or is limited. By the simulation and experimental, it is clarified that the output torque is increased. The system yields less EMI, because of soft switching.
