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.
