Description

A linear voltage-controlled voltage source. Port 1 senses a voltage without drawing current; port 2 is an ideal voltage source of gain times that voltage.

Example

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

Equations

Modelica
v1 = p1.v − n1.v, v2 = p2.v − n2.v
p1.i = n1.i = 0
p2.i + n2.i = 0
v2 = gain · v1
