互感电路的结点电压分析法研究

Research on the Node Voltage Analysis Method of Mutual Inductor Circuit

含耦合电感电路中,耦合电感支路的电压不仅与本支路电流有关,还与其他某些支路电流有关,直接列结点电压方程时会遇到困难。本文采用星形与三角形等效变换,可直接列出电路的结点电压方程,并通过对一个电路的具体分析进行了验证。

In the circuits containing coupling inductance,the voltage of coupling inductance branch is not only depend on its current,but also connected with current of other branches.It is difficult to list the node voltage equation directly.The equivalent conversion of circuits between starlike and triangle is shown in the paper,and the node voltage equation can be listed easily,the method is proved by the specific analysis of the circuit.
