A hybrid converter for high speed operation of switched reluctance motor drives

Switched reluctance motor (SRM) drives have remarkable characteristics, which make them attractive for high-speed applications. In this paper, the basic control strategy for a switched reluctance motor drive circuit is explained. A new power electronic converter is then presented. This topology provides faster rate of rise and fall for the phase current, which permits the motor to operate at higher speeds, hi this hybrid converter, a capacitor is charged through the resonant circuit which consists of the motor phase winding inductance during the phase turn off interval. This capacitor is discharged during the next working stroke into the appropriate phase winding. A detailed description and demonstration of the converter circuit have been included in the digest
