摘要
介绍了并联型功率因数校正(PFC)技术的工作原理,对两种电流控制策略PI控制和无差拍控制在并联PFC技术中的应用进行了分析与比较,重点分析了无差拍控制。在理论分析的基础上,进行了仿真研究。建立了单相并联型PFC系统模型,包括无差拍电流控制模块,给出了系统关键参数,将无差拍控制与PI控制仿真结果进行了比较,验证了无差拍电流控制设计思想的正确性和可行性。
The principle of shunt PFC technology was introduced.The application of two current control strategies used in shunt PFC technology were analyzed and compared,including PI control and dead beat control.The dead beat control was analyzed in detail.Based on theoretical analysis,the simulation study was conducted.The system model of single-phase shunt PFC was built up,including the dead beat current control model.The key parameters design of the PFC system was implemented,and the simulation results of dead beat control and PI control were compared,showing the validity and feasibility of dead beat control design idea.
