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.
