Device for voltage supply with suppression of load response function during reduction of rpm
First Claim
1. A device for regulating voltage in a generator driven by an internal combustion engine and having an exciter winding, the device comprising a voltage regulator which has a control part and a power part and regulates a current flowing through the exciter winding to keep an output voltage of the generator constant, means for additionally limiting an exciting current during occurrence of predeterminable rpm-dependent conditions, said means for additionally limiting the exciting current being operative for triggering said power part of said voltage regulator with a load response travel function formed by said control part of said voltage regulator, and said load response travel function is blocked when an evaluation of an rpm signal makes a conclusion about a dropping rmp.

Abstract
A device for voltage regulation for a generator driven by an internal combustion engine is described in which the voltage regulator is equipped with a load response travel function (LRF), which prevents a rapid rise in the exciting current when a powerful electric consumer is turned on. By means of a suitable trigger circuit which evaluates the engine rpm and thus the generator rpm, the load response travel function is blocked during travel when rpm values are falling, so that in this case, the voltage incursions that occur during an active load-response function are maximally averted.
