Abstract :
The harmonic elimination problem for the PWM is formulated as a set of transcendental equations, and a conventional solution to this problem needs iterative computation. This paper presents a noniterative algorithm based on a trigonometric harmonic cancellation rule among pulses. The effectiveness of the algorithm was confirmed by simulations and experiments.
