摘要：在三相PWM整流器一般数学模型建立的基础上，阐述了坐标变换的原理。并利用同步旋转变换构建了三相电压型整流器（VSR）的dq模型，提出了解耦控制策略，建立了系统的MATLAB仿真模型。利用此模型在MatlabSimulink环境中进行了抗扰性能和能量可逆性的仿真。仿真结果证明，该系统具有很好的动/静态性能、网侧单位功率因数，且能量双向流动。

Abstract: The basic principle of coordinate transformation was presented based on normal mathematic model of threephase voltage source PWM rectifier, and dq model making use of synchronous frame was set up. Then decoupling control strategy was put forward .Matlab simulation model of the system was established. The system was simulated using the model under the environment of Matlabsimulink on reversible energy and resisting disturbance. The simulation results shows that this system has fine static, dynamic performances, unity power factor and energy can be reversible.
Key words: pulsewidth modulation(PWM); voltage source rectifier(VSR); voctor control; synchronous frame; simulation
