A rotating rectifier assembly includes a metallic housing, a composite substrate, and a rectifier subassembly that can be used to rectify a polyphase AC current. The composite substrate includes a ceramic component and one or more metallic components according to a metallization process. The composite substrate and rectifier subassembly may be positioned in an annular cavity within the metallic housing. In applications where excessive heat and/or shock and vibration are present, an encapsulant may be used to fill the annular cavity.

L'invention concerne un ensemble de redressement rotatif qui comprend un logement métallique, un substrat composite, et un sous-ensemble de redressement pouvant être utilisé afin de redresser un courant alternatif polyphasé. Le substrat composite comprend un composant céramique et un ou plusieurs composants métalliques en fonction d'un procédé de métallisation. Le substrat composite et le sous-ensemble de redressement peuvent être positionnés dans une cavité annulaire à l'intérieur du logement métallique. Dans des applications où une chaleur excessive et/ou des chocs et des vibrations sont présentes, un agent d'encapsulation peut être utilisé pour remplir la cavité annulaire.
