Abstract

This paper presents a control strategy for an active neutral-point-clamped five-level (ANPC-5L) inverter using current harmonic minimum pulse-width modulation (CHMPWM) method. This strategy is used to reduce the total current harmonics and limit selected harmonic amplitude with the help of Genetic Algorithm(GA). Two fitness functions are proposed to calculate the initial switching angles by GA for different modulation index. Then, the expected switching angles can be get by substituting the initial switching angles into the fmincon function. Simulation generated by MATLAB are presented to confirm the feasibility of the proposed control strategy.
