【Abstract】 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.更多还原
