Multi carrier PWM and selective harmonic elimination technique for cascade multilevel inverter

This paper presents the multi carrier pulse width modulation (MCPWM) and selective harmonic elimination (SHE) technique for cascade multilevel inverter (CMI) to reduce the total harmonic distortion (THD) of the output voltage waveform. A comparison has been done between the SHE and MCPWM technique to show the advantage of SHE technique over the MCPWM technique. To find the accuracy of total harmonic distortion (THD) between the MCPWM and SHE technique is achieved by comparing the FFT based result for nine level cascade multilevel inverter.
