Implementation ID: ac-current-source
Reviewed: 2026-10-27

Behavior

Conserving component solved simultaneously with the connected network. Analytic sinusoidal current, positive from p to n

Interface

Original Lemonergy interface view. Lines identify ports; they are not a completed simulation circuit.

Ports and observed outputs
Name	Direction	Unit	Meaning
`p`	terminal	V; A	electrical conserving connection; voltage across and current through the connected branch.
`n`	terminal	V; A	electrical conserving connection; voltage across and current through the connected branch.
`current`	output	A	Recorded current measurement from the conserving simulation.
`voltage`	output	V	Recorded voltage measurement from the conserving simulation.
`power`	output	W	Recorded power measurement from the conserving simulation.

Parameters

Defaults are initial model values. Select values for your own model and operating conditions.

Configuration fields
Parameter	Unit	Default	Meaning and limits
Peak current `amplitudeA`	A peak	1	Peak sinusoidal current before the current bias is added. Minimum 0; Maximum 1000000
Frequency `frequencyHz`	Hz	1	Number of sinusoidal cycles per second. Minimum 0; Maximum 1000000
Initial phase `phaseRad`	rad	0	Angular phase added to the sinusoid at time zero. Minimum -1000000; Maximum 1000000
Current bias `biasA`	A	0	Constant current added to the sinusoid. Minimum -1000000; Maximum 1000000

Equations and rules

I(t) = Ibias + Ipeak sin(2π f t + phase)

Analytic sinusoidal current, positive from p to n
Demonstration parameters are not calibrated hardware data. Singular or incompatible ideal constraints and unsupported state ranges stop the run.
