| 摘 要： | 矩阵变流器的拓扑结构采取一个整流级连接逆变级,中间直流环节没有体积庞大的储能环节,使系统具有较高的功率密度、较高的功率因数和良好的输入输出波形。对基于间接矩阵变流器的调制策略进行了深入的研究。采用空间矢量调制策略对整流级和逆变级进行了调制。仿真验证了控制策略的正确性。

| Abstract: | The topology of indirect matrix converter adopts a structure of a rectifier stage connecting several inverter stages. There is no bulky energy storage component in DC link, so the power density of the system is improved. In addition, the system has the advantages of high power factor and perfect input/output waveform. It is suitable for the occasions of AC speed regulating system and other control. The modulation strategy based on indirect matrix converter is researched deeply, and SVM strategy is used for modulation of rectifier stage and inverter stage. The feasibility and validity of proposed modulation strategy are verified by the simulation. |
