Abstract:
A method for controlling or regulating a generator, said generator (10) comprising three stator windings (U, V, W) and three generator terminals (KI.U, KI.V, KI.W) connected with the three stator windings respectively, and wherein said generator terminals are connected with a converter bridge (11) for producing a direct current (IG), said converter bridge including controllable switch elements (15 to 20), and means for controlling said switch elements are provided; said method comprising the steps of:a) measuring a current of said generator or said converter bridge with a current detector (24) to obtain a measured current value; and b) controlling said switch elements (15 to 20) of the converter bridge (11) according to said measured current value, said controlling comprising temporarily connecting at least one of said stator windings to a charge source (21), said charge source (21) being a battery or capacitor, independently of natural turn-on or ignition times of said switch elements, in order to supply said at least one of said stator windings with an additional charging current in addition to any induced current present in said stator windings during an otherwise currentless time interval, so that said generator is supplied with additional magnetizing current.
