Abstract: Motor performance and life is decreased due to presence of harmonic in the output voltage. Many inverter topologies were proposed for industrial drives application. PV based three phase asymmetrical cascade nine level inverter fed induction motor is proposed in this article. The proposed circuit has one dc source derived from PV with MPPT and nine level inverter with reduced components. The PV output voltage is regulated with help of boost converter using MPPT algorithm. The proposed inverter has unequal voltage source 1:2:4 ratios. The fundamental frequency modulation method is used for control the inverter output voltage. The proposed multi level inverter has less switching device and diode compare than other multilevel inverter topology. The circuit is modified further by replacing switching device with diode in the source section for reducing switching count; as a result, the control algorithm and driver circuit complexity are reduced further. The circuit performance is verified with help of simulation results.
