(DE) UMRICHTERSYSTEM UND VERFAHREN ZUM BETREIBEN EINES UMRICHTERSYSTEMS
Abstract:
(EN) The invention relates to a converter system and a method for operating a converter system with a feedback function, in particular a block-type feedback function, having at least the following: - an inverter (101), in particular a first inverter, which feeds back into an alternating voltage supply network, - a DC/DC converter (102) with an actuation unit, and - an electric motor which can be fed by a second inverter, wherein the direct voltage-side connection of the second inverter is connected to a first connection of the DC/DC converter (102), and a current detection means for detecting the current conducted from the DC/DC converter (102) to the direct voltage-side connection of the feedback inverter (101) is connected to an actuation unit, in particular such that the current values detected by the current detection means are supplied to the actuation unit. The actuation unit of the DC/DC converter (102) supplies actuation signals such that the voltage provided to the feedback inverter (101) from the DC/DC converter (102) can regulate, in particular regulates, the detected current to a target value curve.
(FR) L’invention concerne un système convertisseur et un procédé de fonctionnement d’un système convertisseur muni d’un dispositif de réinjection d'énergie notamment en blocs, comprenant : au moins un onduleur (101), notamment donc un premier onduleur, de réinjection d'énergie dans un réseau d’alimentation à tension alternative ; un convertisseur continu/continu (102) muni d’unité de commande ; un moteur électrique pouvant être alimenté par un deuxième onduleur. La borne côté tension continue du deuxième onduleur est reliée à une première borne du convertisseur continu/continu 102. Un moyen de détection de courant destiné à détecter le courant circulant du convertisseur continu/continu (102) à la borne côté tension continue de l’onduleur (101) de réinjection d'énergie est relié à une unité de commande, en particulier de sorte que les valeurs de courant qui sont détectées par le moyen de détection de courant sont fournies à l'unité de commande. L’unité de commande amène au convertisseur continu/continu (102) des signaux de commande tels que la tension fournie par le convertisseur continu/continu (102) à l’onduleur (101) de réinjection d'énergie peut réguler, en particulier régule, le courant détecté suivant une courbe de valeurs de consigne.
