Abstract :
The cost of the electronic drive for a switched-reluctance motor (SRM) is relatively high compared to the SRM itself; this problem is common to most motor drives. However, since SRM torque production is independent of the direction of phase current, the phase excitation can be comprised of unipolar currents. This implies only one switching device per phase is needed. In addition, a high power quality utility interface can be accomplished with only two controllable switches. This paper details the design and operation of the SRM drive and its mating utility interface. The drive is fully regenerative and operates at high power factor with only four controllable switches.
