Abstract

A multilevel inverter is mainly used to synthesize a near sinusoidal voltage from several levels of dc voltages. As number of levels increases, the synthesized output waveform has more steps, which provides a staircase wave that approaches a desired waveform. The harmonic distortion of the output wave decreases, approaching zero as the number of voltage levels increases. This paper spotlights the performance analysis of a five level inverter with coupled inductors. It reduces the total harmonic distortion in the output voltage waveform by using a single dc source. It is capable of solving capacitor voltage unbalance problem. A PI controller is used to regulate the output voltage of the inverter. The sinusoidal pulse width modulation scheme has been used to control the switches. With sinusoidal pulse width modulation, several pulses are produced per half cycle. The main objective of the work is to obtain a five level ac output voltage and to analyze the performance of the multilevel inverter. The MATLAB/ Simulink software package is used to analyze the results.
