Design of three-phase SPWM inverter system based on DSP

Jiang Ma

Abstract

This paper describes the basic structure of the chip TMS320F2812 of TI and the SPWM production method,produces three-phase SPWM using the event supervisor entire comparison function through the symmetrical regular sampling law.And it has given the structure and design of inverter system,some source program code and the experimental results.The experimental results show that the three-phase SPWM which is produced by symmetrical regular sampling law can meet the needs of the inverter system and have good feature.
