Abstract

The implementaton of multilevel inverter at present scenario are more demand for various major industrial application, utility system, traction drives, etc due to its implementation of medium voltage and high power. Various semiconductor switches consists an array like structure to form a multilevel inverter. The required signal of output waveform can be generated and controlled by gate pulses. In case of multilevel inverter of casdaded type, separate dc sources required to produce the voltage waveform in staircase pattern which is nearly similar with the waveform of sinusoidal. The distortion can be decreased by implementing the principle of multicarrier pulse width modulation (PWM). Further THD can also be decreased with rise of number of level. In this paper, the THD analysis is done by using MATLAB for different loads.
