结合三相电压型PWM整流器的数学模型，引入三相电源电压前馈补偿，提出三相电流解耦的双闭环PI调节控制方法。根据控制系统响应速度快、保护功能强的要求，设计了以TMs320LF2407A为核心的控制系统，给出具体硬件电路和详细软件流程。实验结果验证了控制方法和控制系统的有效性。

Based on the mathematic model of a three-phase high-power-factor PWM rectifiert voltage disturbance compensation is added to the controller and double-closed-loop PI controller is presented. In view of the requirements of response speed and protect function, the control system is designed based on the chip TMS320LF2407A. The design of hardware and software is present. Experiment results verify the control scheme.
