modelVariableInductor
Ideal linear electrical inductor with variable inductance
Extends from ComplexLib.SinglePhase.Interfaces.OnePort (Passive component having two ComplexPins p and n (one port) and using current phasor balance).
Information
The linear inductor connects the branch voltage phasor v with the branch current phasor i by
jωL*i = v.The phase shift between voltage and current is 90°.
The inductance L is specified by input signal.
Attention!!!
To ensure that the phasor domain-based model works in a quasi-stationary
mode, the inductance L may alter only very slowly in comparison
with both the nominal frequency f=ω/(2π) and the dominant
time constant of the phasor domain-based model.
Remark:
It is required that L ≥ 0, otherwise an assertion is raised.
