Damit koennen die Netzrueckwirkungen minimiert werden. Fig. 4{Verfahren; Synchronisation; Eingangsstromrichter, mehrere; Leistungsbedarf; Master; Versetzung; Grundwelle; Stromrichtereingangsspannung}Several parallel-operated input converters can be offset with the invention operate by synchronizing to the fundamental of the converter input voltage of the power converter, which has the highest power component.

Description
Ändern sich die Leistungsverhältnisse und ein anderer Eingangsstromrichter übernimmt die Masterfunktion, wird dieser Funktionswechsel durch eine festgelegte Hysterese bzgl. des Leistungsbedarfes und eines zeitlich definierten Steuerregimes ermittelt, d. h. zum Zeitpunkt eines Stromnulldurchgangs oder zu einem anderen geeigneten Zeitpunkt. Die anfangs festgelegte Reihenfolge bleibt dabei erhalten.If the power conditions change and another input converter adopts the master function, this function change is determined by a defined hysteresis with regard to the power requirement and a time-defined control regime, ie. H. at the time of a zero crossing or at another appropriate time. The initially defined order is retained.
Die Anfangssynchronisation kann dabei auf die Netzspannung erfolgen, es kann aber auch sofort auf die Grundwelle der Stromrichtereingangsspannung eines festgelegten Eingangsstromrichters synchronisiert werden, wobei dann für die Zeit bis zum Herstellen der Synchronität eine kapazitive oder induktive Taktung vorgegeben wird, um für diesen Stromrichter eine von Null verschiedene Phasenlage zur Netzspannung herzustellen, die zur Masterfindung notwendig ist.The initial synchronization can be done on the mains voltage, but it can also be synchronized immediately to the fundamental of the converter input voltage of a fixed input converter, then for the time to establish the synchronous capacitive or inductive clocking is specified in order for this converter from zero produce different phase position to the mains voltage, which is necessary for the mastering.
