Abstract:
(EN) This electric power converting device is provided with: an inverter connected to other ends of windings of an n-phase (where n is an integer at least equal to 3) motor of which one end of each winding is connected in a Y shape, the inverter having n legs each of which includes a low side switch element and a high side switch element; a first phase splitting relay circuit which, for each phase, switches between connection and non-connection, by way of the inverter, of a power supply and the n-phase windings; a sub-inverter having at least one leg connected in parallel with the n legs of the inverter, and connected to said other ends of the n-phase windings; and a second phase splitting relay circuit which switches between connection and non-connection, by way of the sub-inverter, of the power supply and the n-phase windings.
(FR) La présente invention concerne un dispositif de conversion de courant électrique qui est pourvu : d'un onduleur connecté à d'autres extrémités d'enroulements d'un moteur à n phases (n étant un nombre entier au moins égal à 3), une extrémité de chaque enroulement étant connectée sous forme de Y, l'onduleur ayant n branches, chacune comprenant un élément de commutation côté bas et un élément de commutation côté haut ; d'un premier circuit de relais de division de phase qui, pour chaque phase, commute entre la connexion et la non-connexion, par l'intermédiaire de l'onduleur, d'une alimentation électrique et des enroulements à n phases ; d'un sous-onduleur ayant au moins une branche connectée en parallèle aux n branches de l'onduleur, et connecté auxdites autres extrémités des enroulements à n phases ; et d'un second circuit de relais de division de phase qui commute entre la connexion et la non connexion, au moyen du sous-onduleur, de l'alimentation électrique et des enroulements à n phases.
(JA) 電力変換装置は、一端同士がY結線されたn相(nは3以上の整数)モータの巻線の他端に接続され、各々がローサイドスイッチ素子およびハイサイドスイッチ素子を含むn個のレグを有するインバータと、電源とn相の巻線との、インバータを介した接続・非接続を相毎に切替える第1相分離リレー回路と、インバータのn個のレグと並列接続された少なくとも1個のレグを有し、n相の巻線の他端に接続されるサブインバータと、電源とn相の巻線との、サブインバータを介した接続・非接続を切替える第2相分離リレー回路と、を備える。
