`VoltageSource`

Ideal voltage source whose output voltage is determined by a real input signal and a scaling parameter.

This component models an ideal voltage source. The voltage v across its positive and negative pins (inherited from the TwoPin base component) is determined by an external real input signal connected to its V input port, and a unit parameter uV. The signal at input V is treated as a dimensionless value, which is then multiplied by the parameter uV (which has units of Voltage) to produce the actual output voltage v across the pins. The relationship is given by:

\[v = V uV\]

Where V is the value of the signal at the RealInput port.

Usage

VoltageSource(uV=1.0)

Connectors

p - This connector represents an electrical pin with voltage and current as the potential and flow variables, respectively. (Pin)
n - This connector represents an electrical pin with voltage and current as the potential and flow variables, respectively. (Pin)
V - This connector represents a real signal as an input to a component (RealInput)

Variables

Name	Description	Units
`v`	Voltage across the component (between pin p and pin n).	V
`i`	Current flowing through the component (from pin p to pin n).	A

Behavior

\[ \begin{align} v\left( t \right) &= \mathtt{p.v}\left( t \right) - \mathtt{n.v}\left( t \right) \\ i\left( t \right) &= \mathtt{p.i}\left( t \right) \\ \mathtt{n.i}\left( t \right) + \mathtt{p.i}\left( t \right) &= 0 \\ v\left( t \right) &= \mathtt{uV} V\left( t \right) \end{align} \]
