Abstract :
A simple and low-cost method of generating the pulse width modulation specific harmonic elimination (PWM-SHE) switching signals to drive the three-phase voltage source inverter (VSI) is presented. This novel approach computes the switching angles online using a PC and provides the flexibility of eliminating different sets of VSI output harmonics in a quick and easy manner without any hardware change. The validity of selected results has been verified experimentally.
