Current Source AC
Purpose
Generate sinusoidal current
Library
Electrical / Sources
Description
The AC Current Source generates a sinusoidal current between its two electrical terminals. The direction of a positive current is marked with an arrow. The momentary current \(i\) 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 current waveform is produced.
Note
A current source may not be open-circuited or connected in series to an inductor or any other current 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 current, in amperes \((\mathrm{A})\). The default is
1.- Frequency
The angular frequency \(\omega\), in radians per second \(\left( \frac{\mathrm{rad}}{\mathrm{s}} \right)\). 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 current
The source current in amperes \((\mathrm{A})\).
- Source voltage
The voltage measured across the source, in volts \((\mathrm{V})\).
- Source power
The instantaneous output power of the source, in watts \((\mathrm{W})\).
