摘　　要：分析了PWM整流器基于空间矢量调制的直接功率控制(DPC-SVM)的原理,对三相控制系统的各个部分进行了详细的阐述。该控制结构为直流输出电压外环,功率控制内环。利用Matlab/SimuLink软件建立系统模型进行仿真研究,得到了各个电气量的实时波形。仿真结果表明,该方法控制效果优异,电流畸变小,具有良好的动静态性能,系统能够很好地实现有功功率和无功功率的控制,同时确保输入侧功率因数为1,方案切实可行。The principle of PWM rectifier DPC-SVM was analyzed and each part of three-phase control system was also demonstrated in detail. The control system bad a closed-loop voltage controller in outer loop and a closed-loop power controller in inner loop. Also, a model was developed making use of Matlab/Simulink. Simulation results show the perfect control effect, less current aberrance, the system has good dynamic and static performances and can realize the control of active power and reactive power independently as well as unit power factor. This scheme is feasible.
