摘　　要：通过把矩阵变换器等效为虚拟的交 直 交变换器 ,将SPWM控制技术应用于其中 ,提出了矩阵变换器的SPWM控制策略。应用DSPTMS32 0C2 4 0对控制系统进行了设计 ,使该系统不仅满足了矩阵变换器对控制实时性的要求 ,性能良好 ,而且使系统的软、硬件电路的设计变得简单、灵活。In this paper,the matrix converter(MC)is considered as a virtual AC DC AC converter.Sine pulse width modulation(SPWM)control technique is applied to control it.Thus a new control strategy for MC is presented.The control system based on the strategy is designed by using digital signal processor(DSP) TMS320C240.The system not only meets the requirement to real-time control and demonstrates high performance,but also simplifies the software and hardware of the system.A prototype of MC is made,and the results of experiment verify the feasibility of the SPWM control strategy and the system desing.
