Abstract
The method for regulating a generator including three stator windings (U, V, W) and a converter bridge ( ) including controllable switch elements ( to ) includes temporarily connecting the stator windings (U, V, W) in an otherwise currentless time interval with a charge source ( ) that supplies an additional charging current to the stator windings (U, V, W) in addition to induced current present in the stator windings (U, V, W). The additional charging current provides the generator ( ) with additional magnetic energy. In a preferred embodiment of the method, the supply of additional charging current to the stator windings is controlled by a logistics element ( ) for setting a turn-on time and a longest on-time duration of at least one switch element and a comparator ( ) that produces a comparison output according to a comparing of an actual current value with a predetermined maximum value.
