摘要/Abstract

摘要： 针对功率变流器传导电磁干扰建模与预测方法展开研究，提出了多通路并联的"干扰源-耦合通路"频域模型，研究了干扰源频谱及干扰耦合通路传递函数的建模提取方法.通过提取干扰源的端口频谱特性及干扰耦合通路的传递函数，直接在频域计算干扰噪声，具有建模方法简单，通用性强，不受具体电路结构限制的特点，可作为通用的频域建模方法应用于功率变流器传导电磁干扰建模与预测研究.通过具体实例，阐述了所提出的多通路频域模型的建模流程，验证了模型的准确性及其在变流器传导干扰建模、预测与噪声抑制过程中的指导意义.

Abstract: Multiple-paths paralleled "Source-Coupling Path" frequency domain model was proposed for conducted interference modeling and prediction in power converters. The modeling approach of noise source spectrum and coupling path transfer function was studied. In the proposed model, the spectrum of noise source and transfer function of coupling path were extracted to calculate noise spectrum in frequency domain. The proposed modeling method is simple and not limited to specific circuit structure, which could act as general frequency domain modeling approach for conducted interference modeling and prediction in power converters. Specific sample was used to illustrate the modeling procedure of the multiple paths frequency domain model, which verified its guidance for conducted interference modeling, prediction and suppression in power converters.

Key words: electromagnetic compatibility, conducted interference, frequency modeling, noise suppressing, spectrum analysis, lumped model
