abstract
A modified dump resistor converter topology for star-connected switched reluctance motors suitable for low-voltage applications is proposed. A dual time constant freewheeling circuit has been designed to improve the drive performance and efficiency over a wide range of speeds. Various modes of operation of the converter are discussed, and a comparison is made with other converter configurations.
