摘　　要：分析了三相电压型PWM整流器系统的拓扑结构,建立了电压型PWM整流器(VSR)在dq,坐标系下的数学模型。采用直接电流控制策略和双闭环控制结构,按此结构确定PI控制器的参数。在Matlab/Simulink环境中建立了仿真模型,结果表明所设计的整流器具有优良的稳态性能和快速的动态响应性能,实现简单,具有一定的实用价值。设计了一台10 kW的样机,用TMS320F2812实现了整个控制过程,得到了满意的功率因数校正结果。This paper analyzes the topology of three-phase voltage-type PWM rectifier system（VSR.）The VSR in the d,q coordinate system mathematical model is built.This paper developes direct current control strategy and voltage-current dou-ble-loop control,based on the method the coefficients of PI controllers.A simulation model in Matlab/Simulink environment is established.The simulation results show that the design of the rectifier has an excellent steady-state performance and a fast dynamic response performancei,ts’ easy to carry outt,he design has a certain degree of practical value.The whole control process is carried out with TMS320F2812.The experiment shows that the satisfied PFC result is got.
