Abstract
This paper deals with the reduction of harmonics & amplitude boosting in polyphase inverters using 60° PWM technique. Using 60° PWM technique total harmonic distortion of output voltage is greatly reduced when compared with 180° and 120° degree mode of conduction techniques. All the triple harmonics present in the output voltage is eliminated so that required filter size can be reduced. The amplitude of output voltage is also augmented as compared to SPWM technique. The results from a MATLAB simulation done for a polyphase inverter to obtain 3-Φ, 445V (peak), 50Hz sinusoidal supply using 60° PWM is used to substantiate this study.
