Elimination of Lower Order Harmonics in Seven-Level Cascaded Inverters

Abstract:

This paper deals with an elimination of lower order harmonics in the seven - level cascaded inverters. The main objective of selective harmonic elimination pulse width modulation strategy is eliminating lower order harmonic by solving nonlinear equations, while the fundamental component is satisfied. In this paper, the Particle Swarm Optimization (PSO) is applied to a seven-level inverter for solving the nonlinear equation. With the proposed approach, the required switching angles are computed efficiently by PSO algorithm. Lower order harmonics up to the 7^th are eliminated. Simulation results verify the proposed method.
