| 摘 要： | 为了设计三相电压型PWM整流器系统,需要建立系统仿真模型进行控制方案和参数的验证,首先由整流器拓扑结构得到了同步旋转坐标系下的数学模型,根据此模型建立了基于电压外环和电流内环的双闭环控制系统,并给出了具体设计方法。采用简化的SVPWM控制策略来实现整流器电流控制的目的,通过Matlab/Simulink对系统进行了仿真,仿真结果表明整流器能够输出稳定的直流电压,实现了能量的双向流动和单位功率因数运行,从而验证了该设计方案的正确性。

| Abstract: | In order to design three-phase voltage-type PWM rectifier system,control method and parameters should be verified by system simulation model.By the three-phase voltage-type PWM rectifier topology,the rotating coordinate system mathematical model was gotten.According to this model,double closed-loop control system was established based on the inner current loop and outer voltage loop,and gave control system design.Using simplified SVPWM control strategy to achieve the rectifier current control,the system was... |
