Power switching modular element and dismountable assembly of a plurality of modular elements

Abstract

The invention relates to a modular element () comprising a stratification of first and second electroconductive plates (PH, PB) which are separated by an intermediate dielectric layer (CD) and at least one electronic power switching chip (CP, CP) which is implanted between the first and second plates, the chip having a upper face comprising a first power electrode and a switching control electrode and a lower face comprising a second power electrode, and the first and second power electrodes being in electrical continuity respectively with the first and second plates. According to the invention, the modular element comprises a plurality of openings (OG, OA, OB, OC, OD) extending into the stratification from outer surfaces of the first and second plates and perpendicularly to said outer surfaces, the plurality of openings comprising at least one first opening (OG) communicating with the switching control electrode and at least one second opening (OA, OB) passing through the entire stratification, the first and second openings each comprising a dielectric layer (DE) and an electroconductive layer (CI), and the electroconductive layer of the first opening being electrically connected to the switching control electrode.
