This paper presents a new approach for harmonic reduction the usage of multi-level casdaded H-bridge voltage supply single phase inverter. In order to increasing the high-efficiency and low Total Harmonic Distortion (THD), it bought the output voltage waveform to almost sinusoidal waveform. In this approach expected to end result to put off positive harmonics or to minimize a current distortion in the induction motor and it operated system smoothly. In performed, the multi-level casdaded H-bridge voltage source single phase inverter is varying the frequencies at 20 to one hundred hertz for resistance, single-phase induction motor load. Experimental effects are presented to display the suitable performance of the proposed technique.
