I have made model in 2013b and now i have installed matlab 2018a, but it is showing some error?
Simscape Power Systems 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.
