modelIdealCommutingSwitch
Extends from Modelica.Electrical.Analog.Interfaces.ConditionalHeatPort (Partial model to include a conditional HeatPort in order to describe the power loss via a thermal network).
Information
The commuting switch has a positive pin p and two negative pins n1 and n2. The switching behaviour is controlled by the input signal control. If control is true, the pin p is connected with the negative pin n2. Otherwise, the pin p is connected to the negative pin n1.
In order to prevent singularities during switching, the opened
switch has a (very low) conductance Goff
and the closed switch has a (very low) resistance Ron.
The limiting case is also allowed, i.e., the resistance Ron of the
closed switch could be exactly zero and the conductance Goff of the
open 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 electrical
behavior 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 quasi-static formulation.
