Abstract
A switched reluctance drive is supplied from a power source. The phases of the machine are controlled by a current chopping controller which uses an excitation strategy to minimize the supply current drawn for a particular output. The strategy is to allow an outgoing phase to freewheel as long as it produces positive torque while the incoming phase is excited.
