REGENERATIVE UNIPOLAR CONVERTERFOR SWITCHED RELUCTANCE MOTORS USING ONEMAIN SWITCHING DEVICE PER PHASEABSTRACT OF THE DISCLOSUREIn a converter for a switched reluctancemotor, a dump capacitor receives freewheeling currentfrom each phase and resupplies the charge to the dcsupply. In this manner, residual magnetic energy isrecovered and phase current quickly reduced whilethe converter requires only one main switchingdevice and one freewheeling device per phase andthe converter allows a unipolar source to be used.
