| Abstract: | The space vector pulse width modulation （SVPWM） can improve the utilization of DC side voltage, and finds wide applications not only in frequency control systems but also in many other fields. Based on the analysis of the basic principle of SVPWM, this paper details TMS320F28335 SVPWM control algorithm combined with the three-phase H-bridge inverter circuit and achieves SVPWM waves in the case of the inverter circuit with one phase open. Through the combination of hardware and software, the debug and experimental observation worked on DSP experimental platforms and experimental results are given in waveforms. The results show that SVPWM algorithm based on DSP is easy to implement and digitize, meeting the different requirements of the drive signal by power de- vices and facilitating the realization of fault-tolerant control. |
