PSO algorithm support switching pulse sequence ISVM for six-phase matrix converter-fed drives

Abstract

A matrix converter (MC) is an array of power electronic switches that are directly connected from input to output. The six-phase matrix converter (SPMC) is an advanced power electronic converter having three-phase input and six-phase output. The SPMC provides the six-phase output for the six-phase applications. In this paper, the SPMC is operated with the indirect space vector modulation (ISVM). This ISVM is unable to bring the harmonic content below standard value. The value of harmonics should be less than 5% as per the standard IEEE value. The optimization technique is able to reduce the harmonic content in the output to below 5%. The switching state can be optimized to get the best results. Every time the optimum switching state will be selected based on the cost function using PSO algorithm, and the same will be given to the MC. This optimization brings the THD below 5%. The simulation results of the proposed technique are shown in this paper for validating the method.
