Model Modelica.Electrical.Spice3.Basic.Ground
Ground node

Information

Ground of an electrical circuit. The potential at the ground node is zero. Every electrical circuit has to contain at least one ground object.

SPICE does not have an element for the ground node (mass). In SPICE netlists the ground is specified by the node number 0. This Modelica SPICE library demands to describe the ground node by this ground element.

Information

The linear voltage-controlled voltage source is a TwoPort. The right port voltage at pin p2 (=p2.v) is controlled by the left port voltage at pin p1 (=p1.v) via

    p2.v = p1.v * gain.

The left port current is zero. Any voltage gain can be chosen.

Model Modelica.Electrical.Spice3.Basic.H_CCV
Linear current-controlled voltage source

Information

The linear current-controlled voltage source is a TwoPort. The "right" port voltage at pin 2 (=p2.v) is controlled by the "left" port current at pin p1(=p1.i) via

    p2.v = p1.i * transResistance.

The voltage source VNAM has the two nodes NV+ and NV-:

                   VNAM VN+ VN- VALUE_V

The current through VNAM hast to be led through the CCV.

Therefore VNAM has to be disconnected and an additional

node NV_AD has to be added.

    NV_AD -> p1.i
    NV- -> n1.i

On this way the current, that flows through the voltage source VNAM, flows through the CCV.
