Application of PSO to determine the HEPWM switching angles of a three phase cascaded multilevel inverter

This paper presents a harmonic elimination pulse width modulation (HEPWM) of five-level cascaded inverters using particle swarm optimization (PSO). The goal of this switching technique is to eliminate the lower order harmonic and satisfied the fundamental component at the same time. To solve the non...

Summary:This paper presents a harmonic elimination pulse width modulation (HEPWM) of five-level cascaded inverters using particle swarm optimization (PSO). The goal of this switching technique is to eliminate the lower order harmonic and satisfied the fundamental component at the same time. To solve the non-linear transcendental equation for the different modulation index of a five-level inverter with 7/9 switching distribution, the dynamic inertia weight PSO algorithm is applied. The required switching angles are computed efficiently by dynamic inertia weight PSO algorithm for entire modulation index. Lower order non-triplen harmonics up to the 47th are eliminated. Simulation and experimental results verify the proposed method.
