| 摘 要： | 针对间接矩阵变换器(IMC)无零矢量空间矢量调制(SVM)时直流侧输出平均电压存在低频脉动的问题,研究了一种直流侧平均电压为恒值的有零矢量SVM策略,推导了该调制策略的表达式,分析了零电流换流原理,给出了实现框图,并最终搭建了一台基于XE164单片机+CPLD的实验样机。实验结果表明,采用有零矢量SVM的IMC不仅可以满足日益严格的电网电能质量要求,同时输出具有更优异的传动性能。

| Abstract: | Aiming at fluctuation problem of DC-link average voltage with no zero-vector space vector modulation (SVM) strategy for indirect matrix converter(IMC),a SVM with zero vector of IMC is researched,which DC-link average voltage is constant,modulation strategy of IMC is deduced,its zero current commutation principle is analyzed and the experimental prototype based on DSP+CPLD is given.The experimental results indicate that the input and output current are the sinusoidal wave,the the input power factor is unit and the DC-link average voltage is constant. |
