Abstract
The well-established regular-sampled pulse width modulation technique is simplified to produce a strategy with reduced computational complexity, but without leading to a significant deterioration in performance. The technique is particularly suitable for applications requiring ultrasonic carrier frequencies to reduce harmonic distortion and for those closed-loop feedback drive systems that are limited by sampling rates and control algorithm execution times
