第十二章 二端口网络

端口电流,端口电压.

线性无独立源二端口网络

\begin{equation} \begin{bmatrix} \dot{I_1}\\ I_2 \end{bmatrix} = \begin{bmatrix} Y_{11} & Y_{12}\\Y_{21} & Y_{22} \end{bmatrix} \begin{bmatrix} \dot{U_1}\\ \dot{U_{2}} \end{bmatrix} \end{equation}

导纳参数矩阵

\begin{equation} Y = \begin{bmatrix} Y_{11} & Y_{12}\\Y_{21} & Y_{22} \end{bmatrix} \end{equation}

计算方法: \(\dot{U}_1 = 0\) (置短路), \(l_1 = Y_{12}\dot{U}_2\), \(I_2 = Y_{22}\dot{U}_2\)…

同理可得, 阻抗参数矩阵.
