Library

Description

The ideal closing switch has a positive pin p and a negative pin n. The switching behaviour is controlled by input signal control. If control is true, pin p is connected with negative pin n. Otherwise, pin p is not connected with negative pin n.

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 quasistationary formulation.
