摘　　要：建立了三相高功率因数脉宽调制(PWM)整流器简化数学模型,通过该模型反映了PWM整流器的运行状态并分析了系统控制器设计,根据电流内环控制要求,给出了传统PI控制方法不同的参数取值对系统效果的影响。通过引入电网电压干扰补偿,提出了一种基于复合校正的无差拍控制方法,通过仿真验证分析得出了该方法在控制精度,响应速度,工程实现上均优于传统PI控制方法,最后,搭建了实验平台,通过实验波形和数据验证了三相高功率因数PWM整流器简化数学模型和无差拍控制方法的正确性。The simplified mathematical model of three-phase high power factor pulse width modulation（PWM） rectifier was built.By this model,the running state of PWM converter was reflected,and according to the requirements of inner current control,the effect of different parameter selection on the system was analyzed.Through the introduction of the grid voltage disturbance compensation,the dead-beat control based on compound adjustment was put forward.The simulation results prove this method is superior to traditional PI control method in the analysis of the control accuracy,the response speed,and engineering realization.Finally,the experimental platform was set up.The experiment waveform and data verify the correctness of the simplified mathematical model of three-phase high power factor PWM converter and dead-beat control based on compound adjustment.
