Sine Pulse Width Modulation based on TMS320F2812

YU Shou-yi

Abstract

The paper introduces a method for generating SPWM waveform by looking up-table and real-time calculation.The system uses the serial communication between the SCI interface of TMS320F2812 and the RS232 interface of PC.Experiment shows that the variable frequency drives system based on this system has the function of 1～50Hz SPWM and over-current protection.
