Electronic card comprising magnetic elements
First Claim
1. An electronic board comprising:
- a planar substrate having a first side and a second side opposite said first side;
at least a first magnetic core element and a second magnetic core element arranged on said first side of said substrate and each of said first magnetic core element and second magnetic core element having at least two legs passing through said substrate; and
at least two windings, arranged around at least one leg of each of said first magnetic core element and said second magnetic core element;
a third magnetic core element in the form of a plate, arranged on said second side of said substrate and in contact with respective ends of said at least one leg of said first magnetic core element and said second magnetic core element;
wherein a spacing between said first magnetic core element and said second magnetic core element prevents mutual magnetic coupling via said third magnetic core element;
whereby said first magnetic core element and said second magnetic core element, said at least two windings and said third magnetic core element form at least two mutually decoupled magnetic circuits.

Abstract
An electronic board, in particular for a power electronics circuit such as a converter, comprises: a planar substrate having a first side and a second side opposite the first side; at least two magnetic core elements, called the first elements, arranged on the first side of the substrate and each having at least two legs passing through the substrate; and at least two windings, arranged around at least one leg of each first magnetic core; wherein: it also comprises a second magnetic core element in the form of a plate, arranged on the second side of the substrate and in contact with respective ends of the legs of at least two first elements; the first elements, the windings and the second element forming at least two mutually decoupled magnetic circuits.
