摘要
建立了三相电压型PWM整流器在三相静止坐标系和两相同步旋转坐标系下的数学模型,将双闭环工程设计方法应用于PWM整流器,研究了其前馈解耦控制策略。在此基础上结合空间矢量调制(SVPWM)的算法,设计了三相电压型PWM整流器控制系统,并在Matlab的Simulink中进行了系统仿真。仿真结果表明,设计方法可行,具有良好的动静态性能,实现了单位功率因数。
A mathematical model of three-phase voltage-type PWM rectifier is established in the three-phase static coordinate system and the two-phase synchronous rotating coordinate system.The double closed-loop engineering design method is applied to the PWM rectifier and its feedforward decoupling control strategy is studied.On this basis,the three-phase voltage-type PWM rectifier control system is designed with space vector modulation（SVPWM） algorithm.The PWM rectifier model＇s simulation is carried out in Matlab/Simulink.Results show that the design method is feasible and has a good dynamic and static performance,and can achieve unit power factor.
