摘　　要：考虑到单相电压型PWM整流器只有一相的特殊性,提出了一种基于旋转坐标变换的前馈解耦控制策略,通过构建正交虚拟电流完成网侧电流的单相旋转坐标变换和采用前馈解耦控制,实现网侧电流的矢量控制和稳定直流母线电压。在MATLAB/Simulink中搭建了仿真模型和基于RT-LAB的半实物仿真实验平台,结果表明该控制策略能够满足系统要求,验证了所提出的控制策略的正确性和有效性。Due to the only one phase of the single-phase voltage source PWM rectifier, a feed-forward decouple control strategy based on rotating coordinates transform was proposed, by constructing virtual current to complete single phase rotating orthogonal coordinate transformation of net side current. Finally, the MATLAB/Simulink simulation model and simulation experiment platform based on RT-LAB were built up. The results show that the control strategy can satisfy the system requirements, which verifies the correctness and validity of the proposed control strategy.
