Abstract
A voltage controller for a three-phase generator is disclosed in which the phase voltage of the generator is evaluated. This phase voltage is evaluated with the aid of a window comparator with variable thresholds. Via a VCL signal, which switches over each time a threshold adaptation occurs, a frequency-dependent signal can be generated that can be evaluated as a measure for the generator rpm.
