摘要： 针对经典的单相PWM （Pulse Width Modulation）整流器在旋转坐标系下需要虚构与输入电流和电压相正交的电流和电压分量且控制系统复杂的问题，利用等效变换的方法，构建了单相PWM整流器在静止坐标系下控制策略的归一化模型.归一化模型揭示了静止坐标系下的比例谐振控制策略和旋转坐标系下的经典控制策略的内在联系与区别.为进一步简化控制策略，文中还对归一化模型中的电流内环控制结构进行了改进，并给出控制器参数配置准则.最后，通过仿真和实验验证了本文所提出的归一化模型的正确性和有效性.

Abstract: In order to solve the problem that the classical single-phase PWM rectifier needs to fabricate the current and voltage components orthogonal to the input current and voltage in the rotating coordinate system, and that the control system is complex, a normalized control strategy model of single-phase PWM rectifier in the static coordinate system is constructed by using the equivalent transformation method. Based on the normalized model, the internal relations and differences between proportional resonance control strategy in stationary coordinate system and classical control strategy in rotating coordinate system are revealed. In order to simplify the control strategy further, the current inner loop control structure in the normalized model is improved, and the controller parameter allocation criteria are given. Finally, the correctness and validity of the normalized model proposed in this research are verified by simulation and experiment.

Key words: single phase PWM rectifier, normalization model, virtual current, parameter configuration
