Abstract:
(EN) This power conversion device (100) converts power from a power supply (101) into power that is supplied to an electric motor (200) having n phases (n is an integer of 3 or more) of windings. The power conversion device (100) is provided with: a first inverter (110) connected to one end of the winding of each phase of the electric motor; a second inverter (140) connected to the other end of the winding of each phase; a first phase separation relay circuit (120) that switches whether the first inverter is connected with or disconnected from the one end of the winding of each phase; and a first neutral point relay circuit (130) that is connected to the one end of the winding of each phase and that switches whether the one ends of the windings of each phase are connected to or disconnected from each other.
(FR) La présente invention concerne un dispositif de conversion de courant (100) qui convertit un courant provenant d'une alimentation électrique (101) en courant fournit à un moteur électrique (200) comprenant n phases (n est un nombre entier supérieur ou égal à 3) d'enroulements. Le dispositif de conversion de courant (100) comporte : un premier onduleur (110) connecté à une extrémité de l'enroulement de chaque phase du moteur électrique; un second onduleur (140) connecté à l'autre extrémité de l'enroulement de chaque phase; un premier circuit de relais de séparation de phase (120) qui commute entre connexion et déconnexion entre le premier onduleur et la première extrémité de l'enroulement de chaque phase; et un premier circuit de relais de point neutre (130) qui est connecté à la première extrémité de l'enroulement de chaque phase et qui commute entre connexion et déconnexion entre les premières extrémités des enroulements des phases.
(JA) 電力変換装置(100)は、電源(101)からの電力を、n相(nは3以上の整数)の巻線を有する電動モータ(200)へ供給する電力に変換する電力変換装置である。電力変換装置(100)は、電動モータの各相の巻線の一端に接続される第1インバータ(110)と、各相の巻線の他端に接続される第2インバータ(140)と、各相の巻線の一端と第1インバータとの接続および非接続を切替える第1相分離リレー回路(120)と、各相の巻線の一端に接続され、かつ、各相の巻線の一端同士の接続および非接続を切替える第1中性点リレー回路(130)と、を備える。
