摘要
针对三相电压型脉宽调制(PWM)整流器的非线性、强耦合特性和工程设计难以实现等特点,以同步旋转d,q坐标系模型为基础,对PWM整流器模型进行数学分析,提出一种新型双闭环控制策略。数值仿真和实验验证表明该方法能明显提高系统的动、静态性能,同时也表明该方法的正确性和优越性。
Aimming at three-phase voltage source pulse width modulation（PWM） rectifier has the characteristics of nonlinear, strong coupling and be difficult to engineering design, the PWM rectifer mathematical model is analyzed based on synchronous rotating d,q frame, and a new type double closed loop control strategy is proposed.The numerical simulation and experimental validation results show that the method can obviously improve the static and dynamic performance of system.Experimental results show that the method is correct and superiority.
