Description

The Voltage-Controlled Voltage Source block models a linear voltage-controlled voltage source, described with the following equation:

V=K·(V(+)V())

where

VOutput voltage
KVoltage gain
V(+),V(-)Voltages presented at the + and – control ports

To use the block, connect the + and – ports on the left side of the block (the control ports) to the control voltage source. The two ports on the right side of the block (the output ports) generate the output voltage. Polarity is indicated by the + and – signs.

Variables

Use the Variables tab in the block dialog box (or the Variables section in the block Property Inspector) to set the priority and initial target values for the block variables prior to simulation. For more information, see Set Priority and Initial Target for Block Variables.

Parameters

Voltage gain K

The change in the output voltage divided by the change in the control voltage that causes it. The default value is 1.

Ports

The block has four electrical conserving ports. Connections + and – on the left side of the block are the control ports. The other two ports are the electrical terminals that provide the output voltage. Polarity is indicated by the + and – signs.
