A flyback type power converter circuit for switched reluctance motor drives is presented. In this converter circuit, the energy extracted from an off going phase is stored in an additional capacitor. The energy stored is used to either be returned to the source frequently or energize the conducting phase during the conduction interval through the transformer. The additional switch to pass the energy stored in the capacitor to the source or the conducting phase is switched under a relatively low voltage condition. Its switching frequency is relatively high so that the size of the transformer can be reduced. The design guideline for the capacitor and the transformer is described. The effectiveness of the presented converter circuit is compared to other circuits through the analysis and experiment.
