ABSTRACT:
An inductor-capacitor series resonant circuit is connected in series with a thyristor or other unidirectionally conductive semiconductor switch to form a resonant network, one resonant network for each stator phase winding of a switched reluctance motor to be connected in parallel to the stator phase winding. Zero current switching is achieved by selecting the resonant frequency such that the inductor and capacitor resonate in a time period during both turn-on and turn-off of the semiconductor switches. A C-dump circuit is included in one embodiment for increased power transfer efficiency.
