Abstract

The mathematical theory of resultants is used to compute the switching angles in a multilevel converter so that it produces the required fundamental voltage while at the same time cancels out unwanted order harmonics. Experimental results are given for the three dc source case. It is shown that for a range of the modulation index the switching angles can be chosen to produce the desired fundamental while at the same time the fifth and seventh harmonics are identically zero.
