(DE) ELEKTRISCHE ANTRIEBSVORRICHTUNG
Abstract:
(EN) The invention relates to an electric drive device (2) comprising a voltage supply (4) for providing a supply voltage (UV), a three-phase machine (12) having a number of neighbouring phase windings (34, 36, 38) with a respective first and second phase ending (42, 44), as well as a modular multi-level inverter (8) connected between the voltage supply (4) and the three-phase machine (12) and having at least one sub-module series connection (20) which has at least one series-connected sub-module (24) and a filter inductor (26), and which is directed to the first phase ending (42) of an associated phase winding (34, 36, 38) of the three-phase machine (12) by means of an intermediate connection (22), wherein the second phase ending (44) of the phase winding (34, 36, 38) is coupled to the voltage supply (4) in an electrically conductive manner.
(FR) L’invention concerne un dispositif de commande (2) électrique comportant une alimentation en tension (4) pour la préparation d’une tension d’alimentation (UV), une machine électrique rotative (12) pourvue d’un certain nombre d’enroulements de phases (34, 36, 38) adjacents respectivement pourvus d’une première et d’une deuxième extrémité de phase (42, 44), ainsi qu’un convertisseur multiniveau (8) modulaire connecté entre l’alimentation en tension (4) et la machine électrique rotative (12) et pourvu d’au moins un circuit en série de modules partiels (20), lequel comporte au moins un module partiel (24) connecté en série et une inductance de filtre (26), et est conduit au moyen d’une connexion intermédiaire (22) à la première extrémité de phase (42) d’un enroulement de phase (34, 36, 38) associé de la machine électrique rotative (12), la deuxième extrémité de phase (44) de l’enroulement de phase (34, 36, 38) étant couplée de manière électriquement conductrice à l’alimentation en tension (4).
(DE) Die Erfindung betrifft eine elektrische Antriebsvorrichtung (2) aufweisend eine Spannungsversorgung (4) zur Bereitstellung einer Versorgungsspannung (UV), eine Drehstrommaschine (12) mit einer Anzahl von benachbarten Phasenwicklungen (34, 36, 38) mit jeweils einem ersten und zweiten Phasenende (42, 44), sowie einen zwischen die Spannungsversorgung (4) und die Drehstrommaschine (12) geschalteten modularen Multilevelumrichter (8) mit mindestens einer Teilmodulreihenschaltung (20), welche mindestens ein in Reihe geschaltetes Teilmodul (24) und eine Filterinduktivität (26) aufweist, und welche mittels eines Zwischenanschlusses (22) an das erste Phasenende (42) einer zugeordneten Phasenwicklung (34, 36, 38) der Drehstrommaschine (12) geführt ist, wobei das zweite Phasenende (44) der Phasenwicklung (34, 36, 38) elektrisch leitfähig an die Spannungsversorgung (4) gekoppelt ist.
