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.
