Abstract :
Because switched reluctance machines are simple and robust, there are many applications in which they can be advantageously used as generators. However, the pulsed nature of switched reluctance machines causes ripple on the output voltage. For proper control, this ripple voltage must be eliminated from the feedback voltage. A computer model was developed and validated to study various types of signal conditioning on the feedback voltage. A band-reject filter and a synchronous sampled filter were investigated for conditioning the feedback signal and compared to a standard low-pass filter. Both the band-reject and synchronous sampled filters showed improvement in transient responses. The investigated synchronous sampled filter implementation, however, gave steady-state errors under various load conditions
