Abstract
(A1) Integriertes Beschaltungsbauelement auf Halbleiterbasis zur Beschaltung eines elektrischen Netzwerkes zur Absorption von elektrischer Energie aus einem elektrischen Energiespeicher, eines elektrischen Netzwerkes, mit zumindest zwei Anschlüssen zum Anschluss an das zu beschaltende, elektrische Netzwerk, einer elektrischen Widerstandsstruktur und einer Reaktanzstruktur, die zwischen die Anschlüsse geschaltet sind.

 

EP 1845620 A2 UPAB: 20071129 NOVELTY - The component has two contacts (12, 14) for connection to an interconnected electrical network. An electrical resistant structure (16) and a capacitor structure (6) are switched between the contacts, where the capacitor structure has a doped semiconductor substrate region (4) that forms an electrode of the capacitor structure. A dielectric layer (8) is arranged on the substrate region, and a conductive layer is arranged on the dielectric layer, where the conductive layer forms another electrode of the capacitor structure. USE - Used for a protective circuit of an electrical network for absorption of electrical energy from an electrical energy storage of the electrical network in a modern power electronic system. Can also be used in an integrated circuit section such as smart-power-chip. ADVANTAGE - The component is designed such that it creates a power electronic system with less assembling cost, thus achieving load limit, voltage limitation and/or oscillation damping of an electrical network.
