    Abstract: A power converter having a parallel resonant circuit, includes an inverter, a resonant circuit, a transformer comprising a primary circuit and a secondary circuit, control means for the inverter, the inverter being connected to the resonant circuit, which is intended to be connected to an output load via the transformer, the power converter wherein the inverter comprises a first half-bridge and a second half-bridge in parallel with the first half-bridge, a first inductor between the first half-bridge and the resonant circuit, a second inductor between the second half-bridge and the resonant circuit, and in that the first and second inductors have the same inductance and are coupled in the opposite direction to one another.

    Abstract: A process for manufacturing at least one 3D electronic module each comprises a stack of electronic packages and/or printed wiring boards, wherein a stack is placed on an electrically interconnecting system comprising metal leads each having two ends. The process comprises the following steps: starting with a lead frame that comprises metal leads, folding by about 180° the leads in order to obtain what is referred to as an internal frame portion including the folded ends, which are intended to be molded, the other portion, which is what is referred to as an external portion, including the unfolded exterior ends, the two ends of each lead being intended to emerge from the 3D module on a given face cut along Z; depositing on the leads a metal coating; placing the external portion of the frame between two, an upper and lower, protective elements while leaving the internal portion free, and placing the frame and the protective elements on a carrier; placing each stack equipped each with exterior interconnection tabs so as to superpose the exterior tabs on the internal portion; molding, in a resin, the stack, the exterior tabs and the internal portion and thereby partially covering the upper protective element; cutting the resin and thereby leaving flush conductive sections of the exterior tabs and of the ends of the leads and removing the resin from the upper protective element; metallizing the cut faces; removing the carrier; and removing the protective elements in order to expose the leads of the external portion.

    Abstract: A method for fabricating a re-built wafer which comprises chips having connection pads, comprising: fabricating a first wafer of chips, production on this wafer of a stack of at least one layer of redistribution of the pads of the chips on conductive tracks designed for the interconnection of the chips, this stack being designated the main RDL layer, cutting this wafer in order to obtain individual chips each furnished with their RDL layer, transferring the individual chips with their RDL layer to a sufficiently rigid support to remain flat during the following steps, which support is furnished with an adhesive layer, with the RDL layer on the adhesive layer, depositing a resin in order to encapsulate the chips, polymerizing the resin, removing the rigid support, depositing a single redistribution layer called a mini RDL in order to connect the conductive tracks of the main RDL layer up to interconnection contacts, through apertures made in the adhesive layer, the wafer comprising the polymerized resin, the chips with their RDL layer and the mini RDL being the re-built wafer.
