Abstract

This paper presents the novel particle swarm optimization technique to determine the optimum switching angles of multilevel converters so as to produce the required fundamental voltage while at the same time not generate lower order harmonics. This optimization method is applied to transcendental equations characterizing the harmonic content to minimize low order harmonics. All set of solutions are found for seven and eleven levels inverters to show the simplicity and effectiveness of proposed method.
