Variable Inductance Modeling

The example compares two models of a variable inductor.


The variable inductor is used in a series LC filter tuned at the 5th harmonic. This filter is connected to a RL 60-Hz voltage source in parallel with a 300-Hz current source.

Inductance is varied sinusoidally +/- 10 % around its nominal value. Compare filter voltage and current of continuous and discrete models
