The Voltage-Controlled Voltage Source () feature connects a voltage-controlled voltage source between two nodes in the electrical circuit. The input control voltage is defined by selecting one or more additional node pairs.

Specify two Node names for the connection nodes for the voltage source. The first node in a pair represents the positive reference terminal.

There are two options to define the relationship between the control voltage and the resulting voltage. The Use gain method defines the resulting voltage as a single control voltage multiplied by the gain. With Custom expression selected it is possible to select multiple controlling voltages and define the resulting voltage as an arbitrary expression containing these voltages.
