I am getting the following error in SimPowerSystems:
SimPowerSystems cannot solve this circuit. Please check for one the following two possibilities :
1) The circuit solution is undetermined. This problem arises when transformers with no magnetization branch (Rm=inf; Lm=inf) are connected together.
--> Specify a magnetizing branch with finite Rm and/or Lm parameter values.
2) Circuit solution is inuccurate due to a badly scaled circuit. This is usually caused by a too wide range of resistance values (ex 1e-6 ohm and 1e6 ohm in the same circuit).
--> Try to reduce range of resistance values. For example, reduce snubber resistances.
Component: Simulink | Category: Model error
I think I've ruled out number 1 as the transformers have Rm and Lm values.
To debug number 2, I'd like to schedule out all of the resistances and assess the range. Presumably, SimPowerSystems does this when it attempts to solve. Is there a way to do this manually?
Thanks

Same issue, anyone fixed it?

how did you solve part 1
