Multi-Objective SHM-PWM Modulation Technique for CMV Control in 3-Phase Inverters

This paper presents a multi-objective modulation technique based on the Selective Harmonic Mitigation-Pulse Width Modulation (SHM-PWM) technique to control CMV in 3-phase inverters. Since the decomposition of CMV is consist of triplen harmonics, the cost function of the proposed SHM-PWM has been developed to include both triplen and non-triplen harmonics to reduce CMV magnitude, precisely mitigate low order harmonics total harmonic distortion of the output voltage at the same time. To achieve this goal, the cost function has been formalized to mitigate selected triplen and non-triplen harmonics. The theoretical and simulation analyses and results strongly prove that the proposed SHM-PWM technique is capable of dealing with multi-objective modulation techniques.
