摘要
给出了双级矩阵变换器(Two-stage Matrix Converter,简称TSMC)的主电路结构,分析了TSMC的换流策略和双空间矢量调制(Space Vector Modulation,简称SVM)策略。提出了以数字信号处理器为系统的控制核心,通过复杂可编程逻辑器件实现换流和驱动信号输出的软件设计方案。实验结果验证了设计的可行性,证明了TSMC和直接式矩阵变换器(Matrix Converter,简称MC)一样具有优良的输入输出特性。
The main circuit structure of two-stage matrix converte(rTSMC)is given,then the commutation strategy and the double space vector modulation(SVM)strategy of TSMC are analyzed.The software design of making the digital signal pro-cesso(rDSP)as the control core of the system,using the complex programmable logic device(CPLD)to realize the commuta-tion and drive signals output.The experimental results verify the feasibility of the design,it also prove that TSMC has the same excellent input and output characteristics with the direct matrix converte(rMC).
