让添加一个小电阻，与变压器绕组或环路中的其他元件之一串联。

24脉冲电路：
图片不知道为什么放上去是这样

运行总是显示如下错误：
The ideal secondary winding 'transfo_3_winding_3' of transformer block 'Three-Phase Transformer (Three Windings)' forms a loop with either:
- another transformer ideal secondary winding;
- an ideal voltage source;
- a capacitor;
- any combination of the above.
You must add a small impedance (resistance or inductance) in this loop, either in the transformer winding or in series with one of the other elements in the loop.
