ControlledIdealTwoWaySwitch

Controlled ideal two-way switch

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

The two-way switch has a positive pin p and two negative pins n1 and n2. The switching behaviour is controlled by the control pin. If its voltage exceeds the value of the parameter level, the pin p is connected with the negative pin n2. Otherwise, the pin p is connected 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.
