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 we try to increase the number of levels THD reduces. This paper contains different single phase multilevel inver...
