There are complex variations in realistic low-voltage power line network topology framework.In order to study the low-voltage power line transmission channel model,a model to describe the power line network channel topology framework is established in terms of basic characteristics of low-voltage power line network in this paper.

低压电力线网络拓扑结构变化复杂，为了研究低压电力线信道传输模型，根据低压电力线网络的基本特点建立了描述电力线网络拓扑结构的模型，利用模型把低压电力信道作为一个过程去描述，建立了节点信号传输函数来推导低压电力线网络的传递函数。

Relationship between IL and relevant network parameters is presented by network theory. Network structure of EMI power line filter and its computation method for IL are discussed. Common mode and differential mode equivalent circuit model of single-phase power line filter and the high frequency distribution parameters model of filter device are established. Meanwhile, the main characters of soft ferrite are analyzed, and its implement on the EMI power line filter and its equivalent circuit model are given. According to the preceding theory, the software for IL of power line filter and the design of filter inductor are programmed. The difference between the imitative and practical results is analyzed, and the rational of the equivalent circuit model is tested.
