Variable speed constant frequency power conversion with a switched reluctance machine

A converter topology which is capable of four-quadrant (motoring and generation) operation is proposed for the variable speed constant frequency (VSCF) power conversion scheme. The new converter topology for the VSCF power conversion scheme is made of two functional stages. One is a converting stage which consists of six switches and six diodes and it interfaces a three-phase 60 Hz AC supply to provide a single-phase variable-frequency AC source to the next converter stage. The other is the commutating stage through which each phase-winding is energized.<
