A New Resonant Driver for Switched Reluctance Motor

The switched reluctance motor (SRM) drive is receiving increasing attentions from various researchers as well industry as a viable candidate for adjustable speed and servo applications. Combining the unique features of an SRM with simple and efficient power converter that is uses, a superior motor drive system emerges which may be preferable for many applications compared to other AC or AD motor drive systems. Although a number of converters have emerged over the years for SRM drives, but every single driver has its own advantage and draw backs and there has always been a tread-off between gaining some of the advantages and losing some when a new driver is invented [3]. In this paper we present a new drivers zero-current switching. It means all the switching operations are done when the phase current is almost zero and so that it reduces the overall power loss in the switching process also using the resonance phenomenon, it provides faster rate of rise and fall current which helps the motor to operate at higher speeds.
