This paper explores the advantages and implementation of Digital Signal Processing (DSP) TMS 320F2812 to generate gate pulses. The main features of this DSP are elaborated. The technique to obtain gate pulses in different pulse width modulation methods in order to control three-phase voltage source inverter is explained systematically. The steps needed to develop the program are highlighted in detail to control frequency and the duty cycle of PWM waveform. Further Fabrication of gate driver circuit is presented. Experimental results of three-phase voltage source inverter controlling ac drive in variable voltage-variable frequency mode are also given.
