摘　　要：将解结耦思想与空间矢量调制策略相结合,针对矩阵变换器双向开关的物理特性,提出一种基于电压正负切换指令信号的矩阵变换器的解结耦矢量调制策略。依据该调制策略可对矩阵变换器双向开关进行灵活独立控制的同时,还可实现电压型非隔离矩阵整流器输出正、负两种直流电压,具有更强的负载适应性。系统的仿真和实验结果证明所提解结耦矢量调制策略的可行性和有效性。Combining the de-re-coupling idea with space vector modulation （SVM） strategy, aiming at the physical characteristics of bidirectional switches of the matrix converters, the de-re-coupling SVM method based on positive and negative voltage switching command signal for matrix converters was put forward. The modulation strategy can not only achieve flexible and independent control to bidirectional switch, but also achieve positive and negative DC output of the voltage source non-isolated matrix rectifier and make it has the stronger adaptability to load. Simulation and experimental results demonstrate the feasibility and validity of the proposed de-re-coupling SVM method.
