Power component with local filtering

A switching component configured to switch an electrical signal, the switching component comprising:

• a substrate bearing one or several elementary components each ensuring the switching of the electrical signal,
• a baseplate onto which the substrate is fixed, the baseplate being configured to discharge heat emitted in the switchings of the switching component,
• two electrical conductors each connected to one of the elementary components and respectively ensuring the input and the output of the elementary component concerned for the signal to be switched,
• a magnetic core associated with each elementary component and produced in a ferromagnetic material, each magnetic core being in a form of a plate specific to each elementary component arranged between the substrate and the baseplate, the magnetic cores being independent and having no common part, the baseplate and each magnetic core being disposed in the component in such a way that a displacement current between the surrounded elementary component respective and the baseplate induces a magnetic induction in the magnetic core, and in such a way that the path followed by a conduction current of the electrical signal switched by the component does not form a turn around the magnetic core.
