Title (EN) CIRCUIT AND METHOD FOR DETECTING A CREEPING SHORT CIRCUIT IN BRIDGE CIRCUITS
(FR) CIRCUIT ET PROCÉDÉ PERMETTANT D'IDENTIFIER UN COURT-CIRCUIT FURTIF AU NIVEAU DE CIRCUITS EN PONT
(DE) SCHALTUNG UND VERFAHREN ZUM ERKENNEN EINES SCHLEICHENDEN KURZSCHLUSSES BEI BRÜCKENSCHALTUNGEN
Abstract:
(EN) The invention relates to a circuit for detecting a creeping short circuit in bridge circuits (10). The circuit comprises a first capture device (30) for a power loss at a battery-side connection (21) of the bridge circuit (10) to a first counting register (31) and a second capture device (35) for a power loss at an earth-side connection (26) of the bridge circuit (10) to a second counting register (36).
(FR) L’invention concerne un circuit permettant d’identifier un court-circuit furtif au niveau de circuits en pont (10). Le circuit comprend un premier dispositif de détection (30) d’une puissance dissipée au niveau d'un raccordement côté batterie (21) du circuit en pont (10), muni d’un premier registre de comptage (31), et un second dispositif de détection (35) d’une puissance dissipée au niveau d'un raccordement côté masse (26) du circuit en pont (10), muni d’un second registre de comptage (36).
(DE) Die Erfindung betrifft eine Schaltungzum Erkennen eines schleichenden Kurzschlusses bei Brückenschaltungen (10). Die Schaltung umfasst eine erste Erfassungseinrichtung (30) für eine Verlustleistung an einem batterieseitigen Anschluss (21) der Brückenschaltung (10) mit einem ersten Zählregister (31) und eine zweite Erfassungseinrichtung (35) für eine Verlustleistung an einem masseseitigen Anschluss (26) der Brückenschaltung (10)mit einem zweiten Zählregister (36).
