关于全耦合的一道习题的讨论

Discussions on a Problem of Perfect Coupling

本文从关于全耦合的一道习题入手,分别从耦合电感的去耦等效、全耦合变压器的伏安关系、耦合电感等效为流控电压源和磁路及互感的定义出发,讨论了四种解法,剖析了其中的联系。本文的讨论对于深化学生和教师对去耦等效、全耦合变压器、变压器等效电路、磁路和互感定义的理解有一定帮助。

Started from a problem on perfect coupling, this paper presents four solutions and discusses the relation- ship among them. This topic and related discussion cover equivalence by decoupling, perfect coupled transformer, equivalent circuit, magnetic circuit, and the definition of mutual inductance, which are helpful for those who are learning or teaching the course of Electric Circuits.
