VERFAHREN UND VORRICHTUNG ZUR AUTOMATISCHEN REGELUNG VON TEILSTROMSTAERKEN EINES GLEICHRICHTERS

摘要

A reference branch circuit includes a voltage divider. Each of at least one regulated branch circuits includes the collector-emitter circuit of a regulating transistor and a measuring resistance. Each regulated branch circuit is associated with a comparator, which compares voltage across the measuring resistance of the corresponding regulated branch circuit to a reference voltage appearing at a reference tap of the voltage divider in the reference branch circuit. Current passing through each regulated branch circuit is regulated to be equal to the current flowing through the reference branch circuit.
