ABSTRACT:
An angle interpolation circuit for a phase energisation controller receives absolute positions from sensors and interpolates conduction angles for each phase in a switched reluctance machine having one or more phases. It uses a frequency multiplier to generate an integer number of pulses between the edges of the sensor signal for clocking a corresponding counter for each machine phase. The circuit adjusts for variations in the mark/space ratio of sensor inputs by setting the counters' expected values at each sensor edge.
