Electrical Sources
The AC Current Source block represents an ideal current source that maintains sinusoidal current through it, independent of the voltage across its terminals.
The output current is defined by the following equation:
![]()
where
| I | Current |
| I0 | Peak amplitude |
| ω | Frequency |
| φ | Phase shift |
| t | Time |
The positive direction of the current flow is indicated by the arrow.

Peak current amplitude. The default value is 10*sqrt(2), or 14.1421 A.
Phase shift in angular units. The default value is 0.
Current frequency. The default value is 60 Hz.
The block has two electrical conserving ports associated with its terminals.
