Le transistor MOSFET en commutation : Application aux associations série et parallèle de composants à grille isolée

Abstract : The association between several components is one of the key point to increase the power level in power electronics. This problem is encountered either inside the modules - between aIl elementary chips-, or during the converter manufacturing, when power modules are connected together. The aim of this work is not to study again aIl problems encountered in the past, but to carry an extensive analysis on series and paraIlel association of insulated gate components. This begins with a generic approach of the switching ccli, including semiconductors, driver and aIl stray components. Design mIes have therefore been proposed, in order to improve the balancing of electrical constraints, between aIl semiconductors. For parallel association, the major role of cabling has been underlined. For series association an active c1amping circuit has been proposed, based on the knowledge about switching phenomena.
