SWITCH TYPE RELUCTANCE MOTOR REGENERATION SINGLE POLE CONVERTER CIRCUIT HAVING MAIN SWITCHING UNIT FOR EACH PHASE

摘要

In a converter for a switched reluctance motor, a dump capacitor receives freewheeling current from each phase and resupplies the charge to the dc supply. In this manner, residual magnetic energy is recovered and phase current quickly reduced while the converter requires only one main switching device and one freewheeling device per phase and the converter allows a unipolar source to be used.
