Abstract

High amounts of harmonics cause noise and electromagnetic interference to nearby systems. Pulsewidth modulation (PWM) techniques are used to reduce the amount of harmonics near the multiples of switching frequencies. To trim down the noise and electromagnetic interference and improve the quality of the output voltages, different types of constant and variable switching frequency random PWM techniques for dual inverter-fed open-end winding induction motor drive configuration are discussed in this study. Moreover, the vector control technique is used along with random PWM techniques to improve the transient response of the dual inverter.
