F_CCC

Linear current-controlled current source

Information

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

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

    p2.i = p1.i * gain.

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

The corresponding SPICE description

    Fname N+ N- VNAM VALUE

is translated to Modelica:

    Fname -> Spice3.Basic.F_CCC Fname
    (Fname is the name of the Modelica instance)
    N+ -> p2.i
    N- -> n2.i  

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

                   VNAM NV+ NV- VALUE_V

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

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 CCC.

    VALUE -> gain
