Abstract

A circuit for controlling the operation of switched reluctance machines (i.e., motor or generator) having a plurality of phase windings. The circuit slows down the initial "turn off" of the phase windings to eliminate an abrupt reduction in the current flowing therethrough. This reduces the impulse which excites mechanical oscillations in the motor/generator, reduces switching losses in the switching transistors, and reduces the number of harmonics.
