摘要
针对传统升压型功率因数校正(PFC)电路对后级开关管电压应力较大的问题,研究了一种降压型谐波注入三相整流器,对此拓扑结构提出了一种改进型双闭环与电压前馈相结合的控制方式。首先,分析了降压型谐波注入整流器的工作原理;其次,描述了改进型控制方式的优点;之后,设计了控制器并进行仿真实验;最后,搭建了2.4 kW的实验电路。综上,理论分析和仿真实验结果均表明,提出的新型控制方式设计合理,能达到提高功率因数、降低输入侧电流谐波含量、输出低纹波稳定电压的目的。
In order to solve the problem that the voltage stress of the rear switching tube is large in the traditional Boost-type power factor correction(PFC)circuit,a Buck-type harmonic injection three-phase rectifier was exploited and an improved double closed-loop control and voltage feedforward control method for the topology was proposed.Firstly,the working principle of the Buck-type harmonic injection rectifier was analyzed.Next,the advantages of the improved control method was described.Then,the controller and perform simulation experiment was designed.Finally,a 2.4 kW experiment circuit was built.From the above,theoretical analysis and experiment results show that the new control methods have design rationality,which can improve the power factor,reduce the harmonic content of the input current and output a stable low ripple voltage.
