Voltage Source AC
Purpose
Generate sinusoidal voltage
Library
Electrical / Sources
Description
The AC Voltage Source generates a sinusoidal voltage between its two electrical terminals. The voltage is considered positive at the terminal marked with a “+”. The momentary voltage \(v\) is determined by the equation
where \(t\) is the simulation time.
If a variable-step solver is used, the solver step size is automatically limited to ensure that a smooth voltage waveform is produced.
Note
A voltage source may not be short-circuited or connected in parallel to a capacitor or any other voltage source.
Parameters
Each of the following parameters may either be a scalar or a vector corresponding to the implicit width of the component:
- Amplitude
The amplitude \(A\) of the voltage, in volts \((\mathrm{V})\). The default is
1.- Frequency
The angular frequency \(\omega\), in \(\left( \frac{\mathrm{rad}}{\mathrm{s}} \right)\). The default is
2*pi*50which corresponds to \(50\,\mathrm{Hz}\).- Phase
The phase shift \(\varphi\), in radians. The default is
0.
Probe Signals
- Source voltage
The source voltage in volts \((\mathrm{V})\).
- Source current
The current flowing through the source, in amperes \((\mathrm{A})\).
- Source power
The instantaneous output power of the source, in watts \((\mathrm{W})\).
