Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Same example as IMC_YD, but with a time delay between Y off and D on.
Note that a switchYDwithArc is used to avoid unphysical voltage peaks when opening Y connection.
Default machine parameters are used.
