In this paper, a new symmetric multilevel voltage source inverter is proposed which consist less number of switches as compared to conventional multilevel inverter. This new symmetric MLI is able to produce desired value of voltage level with reduced number of switches. Also, multilevel inverter has good harmonic profile that is able to reduce total harmonic distortion without affecting desired output power. Moreover, in comparison with conventional cascade multilevel inverter, this new symmetric topology ultimately reduced the number of switches, the number of gate driver circuit, inverter cost, installation area and power loss due to reduced amount of on state switches.
