The concept of inductance in the broad sense is a subject which gave rise to publication from the end of the XIXth century until today. The applications have evolved but the problems are recurrent. Whatever the field, the problem of calculating the inductance and resistance of an electrical circuit is central. In power electronics, this type of component is used for energy storage and must have a minimum of joules losses. This compromise turns out to be difficult to achieve. The objective of this article is the description of the method of dimensioning of non-planar coils which can be adapted to magnetic circuits of the EFD type. We will determine according to its geometric parameters the type of magnetic circuit to be used to reinforce the value of its inductance and the electrical parameters of the Buck type converter, in which the coil will be integrated.

W artykule opisano metodę wymiarowania nie-płaskiego dławika stosowanego w przekształtnikach typu Buck. Podano metodę obliczania indukcyjności oraz strat na ciepło.
