摘　　要：载波相移正弦脉宽调制（SPWM）技术是一种适用于大功率电力开关变换装置的高性能开关调制策略．在有源电力滤波器中有良好的应用前景。本文介绍了如何利用高性能数字信号处理TMS320F28335的片内外设事件管理器（EV）模块产生三相SPWM波，给出了程序流程图及关键程序源码。该方法采用不对称规则采样算法，参数计算主要采用查表法，计算量小，实时性高。在工程实践中表明，该方法既能满足控制精度要求，叉能满足实时性要求，可以很好地控制逆变电源的输出。SPWM technique is a suitable power switch conversion device for high-power high-performance switching modulation strategy. There are good prospects for the application of active power filter. This article describes how to take advantage of high-performance digital signal processor TMS320F28335 chip Peripheral Event Manager （EV） module to generate three- phase SPWM wave, preeess flow diagram and the key to the program source code. The method uses asymmetric regular sampling algorithm parameters calculated mainly using the look-up table method, a small amount of calculation, real-time high. In engineering practice, this method can meet the accuracy requirements of control, but also to meet the real-time requirements, and can control the output of the inverter power.
