简述了矩阵变换器的工作原理及显著优点,重点阐述了由输出线电压空间矢量和输入相电流空间矢量相结合的双空间矢量调制及其优化九段调制策略;利用matlab软件中的S函数准确地实现了优化九段调制策略中的九段脉冲,然后利用simulink对该优化调制策略进行了仿真;仿真结果验证了双空间矢量调制策略的优良性能。

In this paper, the operation principle and evident virtue of matrix converter is depicted simply, and double space vector modulation technique, which combines output line voltage space vector modulation and input phase current space vector modulation,and optimized nine-segment modulation strategy is emphasized; the optimized nine-pulses is produced exactly by using s-function in matlab software, and this modulation strategy is simulated by simulink. The perfect capability of this strategy is verified by the simulation result.
