提出了一种新型分离式三相PFC(功率因数校正)系统结构,并应用单周期控制技术实现了三相整流器的单位功率因数。该方法不需乘法器,简化了系统,并且分离式的结构满足了用户的不同需求。使用matlab的simulink仿真工具建立了该系统的仿真模型,仿真实验结果验证了该系统的有效性。

A new circuit of separable three-phase PFC（power factor correction） was proposed. One-cycle control strategy was applied to achieve unity power factor in three-phase rectifier. This system has separable structure which can meet user＇s different requirements .It＇s simple to implement without multipliers. To evaluate the system performance, simulation model was built using simulink in matlab. Simulation results verify the effectiveness of this system.
