摘要
有源功率因数校正(APFC)技术广泛应用于提高电网适应能力及减小谐波污染的场合,其性能与工作模式及参数设计密切相关。提出基于Boost电感电流数学模型,其分析方法弥补了传统周期平均电流模型不精确、分析范围小的不足,并利用该数学模型系统分析了在断续导通模式(DCM)下Boost PFC电路主要元器件寄生参数对输入电流畸变(THD)的影响。实验验证了理论分析的正确性。
Active power factor correction（APFC）converter performance closely relates to its operation mode and parame-ters design.This paper presents a novel analytical method based on inductor switching current model,and has a systematic analysis about the parasitic parameters effect on total harmonic distortion（THD）of line current in discontinuous conduc-tion mode（DCM）.The novel model has the advantages of accurateness and multiple parameter analysis.The experimental results confirme the validity of the mathematic model and theory analysis results.
