Abstract

The use of the Walsh transform in DC-AC PWM waveform generation allows the calculation of the switching angles by means of linear equations dependent on the fundamental amplitude.

After the description of the mathematical method used to find the solutions, it is presented a method to reduce the computation time needed to find all the switching intervals that give a useful range variation of the fundamental amplitude.
