摘要

This paper presents a novel inverter named nine switch inverter for independent control of two AC motors. The inverter has nine switching devices. The proposed inverter is composed of two conventional inverters with three common switches. A nine switch inverter can achieve the independent control of two ac motors by controlling the MI of the inverters. The simulation model of the inverter is developed in MATLAB/simulink. Two different firing schemes namely PWM and SVM are presented. The performance of the inverter is analyzed with the different switching techniques and compared in terms of THD and switching losses. The simulation results are presented for different modulation indices.
