A New Topology of Hybrid Multilevel Inverter

This paper introduces a modified multilevel inverter topology that has many steps with fewer power electronic switches. The proposed circuit consist of bypassed?diode technique. The optimal structures of this topology are investigated for various objectives, such as minimum number of switches, diodes, total harmonic distortion and minimum standing voltages on the switches for producing the maximum output voltage steps. This new topology use only eight switches, four diodes for the design of 31-level inverter. The working of this multilevel inverter has been studied using both resistive and inductive loads. Validation is provided by conducting simulation studies on a induction motor drive.
