双级矩阵变换器空间矢量调制策略的仿真研究

首先简要地介绍了常规矩阵变换器（Conventional MC）的优点及不足，说明了双级矩阵变换器（TSMC）的优势。接着推导了从常规MC到TSMC的演变过程，证明了两者开关函数等效、变换功能相同。然后介绍了TSMC空间矢量调制（SVM）策略，在此基础上建立了基于MATLAB的TSMC仿真模型，并给出了仿真波形。仿真结果验证了模型及控制策略的正确性。

Simulation Study of Two Stage Matrix Converter Space Vector Modulation Strategy

The advantages and the defects of the conventional matrix converter（CMC） are introduced to explain the strengths of the two-stage matrix converter（TSMC）. Then, the process of topology evolution from CMC to TSMC is analyzed to prove that they have the same switching functions and transform function. The space vector modulation（SVM） strategy of TSMC is introduced, and the simulated model of TSMC based on MATLAB is established, main waveforms are given. The simulation results verify the correctness of the model and controlling strategy.
