摘要
介绍了电压空间矢量脉宽调制技术(SVPWM)的基本工作原理,给出了求解相关参数的公式.介绍了TMS320F2812DSP事件管理器的硬件结构,利用事件管理器可以很方便地产生SVPWM波形,减少了DSP运算单元CPU的工作量并给出了由事件管理器产生SVPWM的流程图.最后给出了实验结果,分析了此种方案的优缺点.
The basic principle of pulse width modulation based on voltage space vectors is introduced, the expressions which can work the correlative parameter is given, and at the same time, EV module of TMS320F2812 DSP is presented. The wave of SVPWM can be generated easily by EV module. By using EV module to generate SVPWM wave can reduce the work of CPU in DSP. The flow chart of how to generate SVPWM wave is given, the advantage and disadvantage of this method throw the results from test are analyzed in the end.
