| Abstract: | 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. |
