[Getdp] Harmonic Formulation for parasitic capacitances?

[Ruth Vazquez Sabariego]

Dear Geoffrey,

That’s a bit more complicated.

Wounded inductors (bobbins) are usually accounted for with a magnetodynamic formulation, that means resistive and inductive effects accounted for.
In a full wave formulation, you would have everything, resistive, inductive and capacitive effects, but it is expensive and may be unstable for low frequencies.

You may also combine/couple two different formulations, a magnetodynamic formulation and an electrostatic formulation.
For the details, have a look at the following paper:
Patrick Dular, Ruth V. Sabariego, Patrick Kuo-Peng, (2006),"Three-dimensional finite element modeling of inductive and capacitive effects in micro-coils", COMPEL: The International Journal for Computation and Mathematics in Electrical and Electronic Engineering, Vol. 25 Iss: 3 pp. 642 - 651

For the implementation: you may mix the inductor model (onelab) and the one you already have.

Regards,
Ruth

Dear all,

How to take into account  the evolution of parasitic pacacitances  with the operating frequency in the case of a wounded inductor? Is there an other formulation to use ?

Thanks for your help,

Geoffrey
