(DE) LUFTSPULE FÜR EINEN MULTILEVELKONVERTER
(EN) AIR-CORE COIL FOR A MULTILEVEL CONVERTER
(FR) BOBINE À AIR POUR UN CONVERTISSEUR MULTI-NIVEAUX
Abstract
(DE)
Die vorliegende Erfindung betrifft eine Luftspule mit mindestens einem Leiterbündel (146), wobei das Leiterbündel (146) aus mindestens vier rohrförmigen, zueinander isolierten Leitern (141a, 141i, 142a, 142i) gebildet ist. Die Erfindung betrifft des Weiteren einen Multilevelkonverter (10) mit einer derartig ausgebildeten Luftspule und ein Luftfahrzeug mit einem derartigen Multilevelkonverter (10).
(EN)
The present invention relates to an air-core coil comprising at least one conductor bundle (146), wherein the conductor bundle (146) is formed from at least four tubular conductors (141a, 141i, 142a, 142i) which are insulated from one another. The invention further relates to a multilevel converter (10) comprising an air-core coil which is designed in this way, and to an aircraft comprising a multilevel converter (10) of this kind.
(FR)
La présente invention concerne une bobine à air comprenant au moins un faisceau de conducteurs (146), le faisceau de conducteurs (146) étant formé par au moins quatre conducteurs (141a, 141i, 142a, 142i) tubulaires isolés les uns des autres. L’invention concerne en outre un convertisseur multi-niveaux (10) comprenant une bobine à air formée de telle façon et un aéronef comprenant un tel convertisseur multi-niveaux (10).
