摘要
介绍了单相PWM整流器的拓扑结构及工作原理,建立了主电路数学模型。根据大信号平均模型设计了电感电流内环和直流母线电压外环的双环控制器,并且对内外环控制器的参数进行了整定。最后介绍了功率因数调节方法,并且用Matlab仿真验证了模型以及控制器的正确性。
Topology and working principle of the single-phase PWM rectifier are firstly introduced in the paper.Then mathematical model of the main circuit is built.According to the large-signal averaging model,a double-loop controller with inner current loop and outer voltage loop is designed whose important parameters are also given.Finally the method of ad-justing power factor is introduced.Simulation results prove the accuracy of the model and controller.
