使用 circuitikz 的变压器物理模型

我想使用 circuitikz 在 Latex 中实现这个变压器模型。我可以绘制变压器、电阻器和电感器等基本元件。但我无法放置带标签的箭头、带标签的圆形箭头以及理想变压器块周围的虚线。我不是这个工具的专家。请帮助我。非常感谢。在此处输入图片描述

这是我使用的代码，当我编译它时，由于所有变量相互重叠，输出看起来有点混乱。有人可以把它拿开并美化一下，使它与上图相匹配吗？

\begin{figure}[h!]
\label{fig:tfmodel}
\begin{circuitikz}[european]
\draw (0,0)
to[short,o-*] (1,0) node[anchor=south]{$K_1$}
to[R, l^=$R_{p}$, v_>=$U_{R_{p}} I_{R_{p}}$, *-*] (3.5,0) node[anchor=south]{$K_2$}

(0,0|-T.A2) to [short, o-*] (6,0|-T.A2)
(T.B2) to [short, -o] (15.5,0|-T.B2);
\draw[dashed] ($(T.south west)+(.2,.2)$) rectangle ($(T.north east)+(-.2,-.2)$)

答案1

以下是一些比较困难的特征。

\documentclass[border=2pt]{standalone}
\usepackage{circuitikz}
\usetikzlibrary{calc}
\begin{document}
\begin{circuitikz}[european]
\draw (0,0) node[above] {$\textrm{K}_1$}
  to[R,l=$R_p$,v=\mbox{$U_{R_p},L_{R_p}$},*-*] (2,0);% \mbox hides the comma from the parser
% Transformer
\node (T) [transformer] at (1,-1) {};
\draw[dashed] ($(T.south west)+(.2,.2)$) rectangle ($(T.north east)+(-.2,-.2)$);
% Loop current.
\node (loop1) at (3,0) {$\textrm{M}_1 +$};
\draw[->] (loop1.west) arc[start angle=180, end angle=-90, radius=.5];
% It is possible to calculate the radius precisely using \pdfextractx
\end{circuitikz}
\end{document}

经过多次尝试，我终于能够完成代码。非常感谢 John Kormylo 的建议。它们真的帮了我大忙。以下是所有更改后的代码和输出。有些人以后可能会发现它很有用。
