基于DSP的SPWM波形设计与实现

With the development of modern control theory and modern industrial progress, requirements for easy implementation of electromechanical control. Due to the SPWM method is implemented as a simple, effective, and has been widely applied to the inverter and motor drive. This article discusses the SPWM principle and present extensively apply sampling methods, comparative analysis of the several advantages and disadvantages of sampling methods; and introduces apply TMS320F2812 chip by checking table generate three-phase SPWM wave. Experimental results show that it meets certain control precision requirements and meet the real-time performance requirements, it is easy to control.
