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.
`branchCurrent`	output	A	Recorded branchCurrent 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 voltage `amplitudeV`	V peak	1	Peak sinusoidal voltage before the voltage 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
Voltage bias `biasV`	V	0	Constant voltage added to the sinusoid. Minimum -1000000; Maximum 1000000

Equations and rules

V(t) = Vbias + Vpeak sin(2π f t + phase)
