Abstract :
A simple and low cost method of generating the PWM specific harmonic elimination (PWM-SHE) switching signals to drive a 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 PSPICE circuit result has been verified experimentally.
