Total Harmonic Distortion (THD) is a term used to describe the net deviation of a nonlinear waveform from ideal sine waveform characteristics. Total harmonic distortion is the ratio between the RMS value of the harmonics and the RMS value of the fundamental. In multilevel inverter as the users try to increase the number of levels THD reduces. This paper contains different single phase multilevel inverter configuration. Different cascaded H bridge type of inverters is pointed out in this paper. Cascaded H bridge type multilevel inverters are built in MATLAB simulation and results are illustrated.
