在 circuitikz 中添加当前路径

这是我的代码：

\documentclass[]{article}
\usepackage{circuitikz}
\begin{document}
\begin{figure}
\centering
\begin{circuitikz}
\draw (0,0) 
  to[short,o-](2,0)
  to[short,*-](4,0)
  to[D](4,2)
  to[D](4,4)
  to[short,-*](2,4)
  to[short,-o](0,4);
\draw (4,0) 
  to[short,*-](8,0)
  to[D](8,2)
  to[D](8,4)
  to[short,-*](4,4);
\draw (2,0)
  to[Tnpn,n=q2](2,2)
  to[Tnpn,n=q1](2,4);
\draw (8,0)
  to[short,*-](10,0)
  to[Tnpn,n=q4,mirror](10,2)
  to[Tnpn,n=q3,mirror](10,4)
  to[short,-*](8,4);
\draw
  (q1.B) to[short,-o](1,3) node[left]{$Q_1$}
  (q2.B) to[short,-o](1,1) node[left]{$Q_2$}
  (q3.B) to[short,-o](11,3) node[right]{$Q_3$}
  (q4.B) to[short,-o](11,1) node[right]{$Q_4$};
\draw (2,2) to[short,*-*](4,2) to[Telmech=M](8,2) to[short,*-*](10,2);
\end{circuitikz}
\caption{Chopper E}
\end{figure}
\end{document}

我想知道是否有可能使用circuitikz绘制电流和一般电位线的路径（一般而言，它们不必指特定的双极子，而是指两个一般点）。

此外，当前路径可能是在后面电路？

例子

笔记：我正在寻找circuitikz包的功能。但如果没有，使用 tikz 的解决方案也可以，但最好不要加载circuittikz 库，否则我必须出于兼容性原因修改大量图形。

\documentclass[]{article}

编辑 要将当前放置在背景层上，请添加\usetikzlibrary{backgrounds}序言，并将其on background layer作为环境选项scope。还根据@Kpym的建议更改了路径

    to[D](4,4)

答案2

这里实现了几乎 90% 的circuitikz宏，具有所有样式选项，电流线是 tikz 宏和decorations库的一部分。观察是，您的绘图中电压的符号是错误的，电流朝向正电压移动。

OBS：我在 中进行编译standalone class，因为我将结果导出为 pdf，然后通过graphicx允许插入 pdf 文档的库将其导入主文档，您可以看到更繁琐的解释这里。

结果： 在此处输入图片描述
