ABSTRACT:
A commutation controller for a switched reluctance machine has separate timer circuits for determining the firing signals for motoring and generating modes. Each timer circuit comprises a ramp generator and a pair of comparators which denote the ON- and OFF-angle as the ramp output passes preset thresholds applied to the comparators. A multiplexer selects the output from one of the motoring and generating timers according to the mode of machine operation. By producing timing signals for the motoring and generating modes separately and continuously, a transition between motoring and generating modes can be carried out smoothly without timing error.
