摘要
针对矩阵变换器电压传输比偏低的问题,提出了一种优化的间接空间矢量的调制策略(新型SVP-WM)。从理论上分析了新型SVPWM调制策略及其提高矩阵变换器电压传输比的性能,建立仿真模型进行仿真实验。理论分析和仿真实验研究均表明:在线性调制范围内新型SVPWM调制策略将电压传输比从传统间接空间矢量的0.866提高到0.955,输出电压及输入电流波形良好,而且控制策略简单,利于实时控制,具有一定的理论研究价值和应用前景。
According to the low voltage transfer ratio of matrix converter, a kind of optimized indirect space vector modulation strategy （novel SVPWM） of matrix converter was proposed. Modulation principle and performance of the strategy on increasing voltage transfer ratio was analyzed theoretically and simulation model was set up. Theoretical analysis and empirical simulation studies show that in the linear range new SVPWM can make the voltage transfer ratio rise to 0. 955 from 0. 866 of conventional indirect space vector control strat- egy. Output voltage and input current waveforms are good. The strategy is simpler and easier to control real- time, and it has theoretical research value and application prospects.
