Description

A linear current-controlled voltage source. Port 1 is a short circuit that senses its current; port 2 is an ideal voltage source proportional to that current.

Example

Controlled sources Voltage- and current-controlled sources and a gyrator, each driving a 10 Ω load.

Ports

Conserving terminals 4

  • 1+p1electrical

    Control input, positive pin. The sensed current i1 flows into p1.

  • 1−n1electrical

    Control input, negative pin. Held at the same voltage as p1.

  • 2+p2electrical

    Output, positive pin.

  • 2−n2electrical

    Output, negative pin.

Parameters

  • TransresistancetransResistance1 Ω

    Transresistance, in ohms. Any real number.

Equations

Modelica
i1 = p1.i, p1.i + n1.i = 0
p1.v = n1.v
v2 = p2.v − n2.v, p2.i + n2.i = 0
v2 = transResistance · i1
