Abstract :
This paper describes two different PWM methods to improve the quality of the output voltage waveform provided from five level inverter. The first one is the selective harmonics elimination (SHEPWM). The purpose is to cancel the 5th, 7th and 11th harmonic row. The second technique is proposed to optimize the total harmonic distortion (OTHD) using the differential evolution method.
