Abstract
This study proposes a power factor correction (PFC)-based half-bridge dual-output converter-fed switched reluctance motor (SRM) drive for home appliances. The proposed converter provides two equal output voltages to feed a mid-point converter of a four-phase SRM. An adjustable speed drive is proposed here such that the speed control is obtained by regulating converter output voltage. The converter is operated in discontinuous conduction mode to obtain inherent PFC at supply side. The sensors requirement is reduced by selecting a voltage follower approach. The performance of proposed drive is evaluated for steady-sate and dynamic conditions. The input current total harmonic distortion is reduced below 5% as per an IEC standard.
