用24个电感通过一定的链接方式仿真一个三相输入三相输出的自耦变压器,最开始没有设置电感的初始电流值,仿真能进行,但是结果不对,三相输出的电压不收敛,发散了
后来把每个电感的初始电流值都设置为很小的值,10毫安,Saber 出现出错信息:

Some possible causes for a singular Jacobian matrix:
- Model operating outside of its intended region of operation.
- Node/subsystem with no connection to the reference (floating).
- Current loops (voltage sources/inductors in parallel).
- Missing equation and/or missing variable reference.
