Abstract

This paper suggests a new 3-phase multilevel inverter that is able to generate 7 levels in line-to-line voltage by only 11 switches. The inverter is designed from the 6-switch conventional full-bridge topology with the adding of 5 bidirectional switches in which 2 of them are shared between the three phases. By performance so, the number of power switches can be minimized, so reducing the complexity in generating and controlling PWM signals. The performance of the inverter and the effectiveness of the modulation technique are verified using MATLAB/SIMULINK.
