Abstract:
1. A power switching cell comprising at least two power components incorporated in a substrate, said substrate being formed of a stack of sheets of dielectric material, each of said at least two power components being incorporated in the thickness of a different sheet of said stack of sheets of dielectric material, each of said at least two power components exhibiting a first face equipped with at least one point of electrical connection and also exhibiting one opposite second face equipped with at least one other point of electrical connection, said at least two power components forming a chain of power components electrically linked in series by way of at least one intermediate electrical connection, said at least one intermediate electrical connection being entirely incorporated inside said substrate, said at least one intermediate electrical connection electrically connecting said second face of one of said at least two power components to said first face of the other of said at least two power components in said chain of power components, said faces of said at least two power components that are unlinked to said at least one intermediate electrical connection being situated at the ends of said chain of power components so as to be disposed in such a way as to be separated from one another by means of said stack of sheets of dielectric of which said substrate is formed.
