Abstract
(DE)
Die Erfindung betrifft ein Steuerungsverfahren eines Stromversorgungssystem mit wenigstens zwei Leistungsteilen (L1, L2, L1', L2'), deren Leistungsausgänge parallel geschaltet sind, wobei jeder Leistungsteil (L1, L2, L1', L2') mittels einer eigenen Steuerung (STR1, STR2) angesteuert wird und wobei jeder Steuerung (STR1, STR2) zumindest eine erste Stromgrenze (S1) vorgegeben ist, bis zu der die Steuerung (STR1, STR2) den zugeordneten Leistungsteil (L1, L2, L1', L2') in einem Normalmodus ansteuert. Dabei ist jeder Steuerung (STR1, STR2) ein erster Absenkungswert (UA, UA') der Ausgangsspannung (UOUT, UOUT1, UOUT2) bei Erreichung der ersten Stromgrenze (S1) vorgegeben und die jeweilige Steuerung (STR1, STR2) regelt bei Erreichung der ersten Stromgrenze (S1) die Ausgangsspannung (UOUT, UOUT1, UOUT2) des zugehörigen Leistungsteils (L1, L2, L1', L2') auf den ersten Absenkungswert (UA, UA'). Ein derartiges Steuerungsverfahren ermöglicht die Parallelschaltung mehrerer Leistungsteile (L1, L2, L1', L2') ohne übergeordnete Steuerung.
(EN)
The invention relates to a control method for a power supply system having at least two power parts (L1, L2, L1', L2'), having power outputs which are connected in parallel, wherein each power part (L1, L2, L1', L2') is actuated by means of a separate control (STR1, STR2) and wherein at least one first power limit (S1) is specified for each control (STR1, STR2), the control (STR1, STR2) actuating the allocated power part (L1, L2, L1', L2') up to said first power limit in a normal mode. According to the invention, a first drawdown value (UA, UA') of the output voltage (UOUT, UOUT1, UOUT2) is specified for each control (STR1, STR2) upon reaching the first power limit (S1), and the respective control (STR1, STR2) regulates the output voltage (UOUT, UOUT1, UOUT2) of the related power part (L1, L2, L1', L2') to the first drawdown value (UA, UA') upon reaching the first power limit (S1). Such a control method enables the parallel connecting of a plurality of power parts (L1, L2, L1', L2') without a super-ordinate control.

La présente invention concerne un procédé de commande d'un système d'alimentation en courant, avec au moins deux parties de puissance (L1, L2, L1', L2'), dont les sorties de puissance sont connectées en parallèle, chaque partie de puissance (L1, L2, L1', L2') étant commandée au moyen d'une commande propre (STR1, STR2) et une première limite de courant (S1) étant prévue pour chaque commande (STR1, STR2), jusqu'à laquelle la commande (STR1, STR2) commande la partie de puissance (L1, L2, L1', L2') associée dans un mode normal. Pour ce faire, une première valeur de réduction (UA, UA') de la tension de sortie (UOUT, UOUT1, UOUT2) est prévue pour chaque commande (STR1, STR2) lorsque la première limite de courant (S1) est atteinte. Lorsque la première limite de courant (S1) est atteinte, la commande respective (STR1, STR2) régule la tension de sortie (UOUT, UOUT1, UOUT2) de la partie de puissance (L1, L2, L1', L2') associée sur la première valeur de réduction (UA, UA'). Un tel procédé de commande permet la connexion en parallèle de plusieurs parties de puissance (L1, L2, L1', L2') sans commande supérieure.
