Abstract
A polyphase switched reluctance drive is supplied from a passive power factor correction circuit. The phases of the machine are switched so that there is substantially always one phase drawing current from the DC link and the current drawn from the DC link is substantially always positive. Embodiments of the invention provide a cost-effective, high-power, switched reluctance drive system that draws power at a high power factor from the supply. Corresponding methods provide similar advantages.
