IdealIntermediateSwitch
Ideal intermediate switch
Library
Modelica/Electrical/QuasiStationary/SinglePhase/Ideal
Description
The intermediate switch has four switching contact pins p1, p2, n1, and n2.The switching behaviour is controlled by the input signal control. If controlis true, the pin p1 is connected to pin n2, and the pin p2 isconnected to the pin n2. Otherwise, the pin p1 is connected to n1, andp2 is connected to n2.
In order to prevent singularities during switching, the openedswitch has a (very low) conductance Goffand the closed switch has a (very low) resistance Ron.
The limiting case is also allowed, i.e., the resistance Ron of theclosed switch could be exactly zero and the conductance Goff of theopen switch could be also exactly zero. Note, there are circuits,where a description with zero Ron or zero Goff is not possible.
Please note:In case of useHeatPort=true the temperature dependence of the electricalbehavior is not modelled. The parameters are not temperature dependent.
Use with care:This switch is only intended to be used for structural changes, not for fast switching sequences, due to the quasistationary formulation.
