| 摘 要： | 针对矩阵变换器在实际应用中存在电压传输比较低的问题,基于空间矢量PWM研究了矩阵变换器的两种过调制策略.在过调制策略中根据电压调制系数不同,给出了参考电压矢量不同的调整策略,以提高电压传输比.在MATLAB下对过调制策略进行了仿真研究,仿真实验结果证实所提出的空间矢量PWM过调制策略能有效提高矩阵变换器的电压传输比.

| Abstract: | For the voltage transferring ratio being low in matrix converter,the two overmodulation strategies are investigated based on space vector PWM.In the overmodulation strategies,the different adjusting schemes of the reference voltages are given to improve the voltage transferring ratio according to the different voltage modulation ratios.The simulation research of overmodulation schemes is carried under MATLAB.The simulation results are showed that the proposed space vector overmodulation schemes can effectiv... |
