Modelica.Electrical.QuasiStatic.SinglePhase.Ideal.IdealCommutingSwitch Modelica.Electrical.QuasiStatic.SinglePhase.Ideal.IdealCommutingSwitch

Ideal commuting switch

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.

Ideal intermediate switch

Information

The intermediate switch has four switching contact pins p1, p2, n1, and n2. The switching behaviour is controlled by the input signal control. If control is true, the pin p1 is connected to pin n2, and the pin p2 is connected to the pin n2. Otherwise, the pin p1 is connected to n1, and p2 is connected to n2.

IdealIntermediateSwitch1

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.

IdealIntermediateSwitch2

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.

Information

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

Information

The ideal transformer is a two-port circuit element without magnetization. Voltages and currents are ideally transformed:

v1 =  v2*n;
i2 = -i1*n;

where n is a real number called the turns ratio.
