The present invention relates to an integrated inverter-charger device. According to one aspect of the present invention, an integrated inverter-charger device may be provided which comprises: a charging unit of which one end is connected to a power input unit for supplying alternating current power, and the other end is provided to a transformer which is isolated into a primary side and a secondary side; a conversion unit which, in a charging mode, converts the alternating current power provided from the charging unit into direct current power for charging a battery, and in an operation mode, converts direct current power provided from the battery into power for driving a three-phase electric motor; a transfer switch unit which comprises at least one transfer switch which is switched so that the conversion unit selectively forms a closed circuit with one between the secondary side of the transformer and the three-phase electric motor; and a control unit which controls the switching of the transfer switch so that in the charging mode, the secondary side of the transformer and the conversion unit form a closed circuit, and in the operation mode, the three-phase electric motor and the conversion unit form a closed circuit.

    La présente invention concerne un dispositif convertisseur-chargeur intégré. Selon un aspect de la présente invention, un dispositif convertisseur-chargeur intégré comprend : une unité de charge dont une extrémité est raccordée à une unité d'entrée de puissance pour fournir une alimentation en courant alternatif, et l'autre extrémité est fournie à un transformateur qui est isolé en un côté principal et un côté secondaire ; une unité de conversion qui, dans un mode de charge, convertit l'alimentation en courant alternatif fournie par l'unité de charge en une alimentation en courant continu pour charger une batterie, et dans un mode de fonctionnement, convertit l'alimentation en courant continu fournie par la batterie en énergie pour entraîner un moteur électrique triphasé ; une unité de commutation de transfert qui comprend au moins un commutateur de transfert qui est commuté de telle sorte que l'unité de conversion forme sélectivement un circuit fermé avec l'un entre le côté secondaire du transformateur et le moteur électrique triphasé ; et une unité de commande qui commande la commutation du commutateur de transfert de telle sorte que, dans le mode de charge, le côté secondaire du transformateur et l'unité de conversion forment un circuit fermé, et dans le mode de fonctionnement, le moteur électrique triphasé et l'unité de conversion forment un circuit fermé.

    본 발명은 인버터-충전기 통합 장치에 관한 것이다. 본 발명의 일 측면에 따르면, 일단이 교류 전원을 공급하는 전원 입력부와 연결되고, 타단이 1차측과 2차측으로 절연되는 트랜스포머로 제공되는 충전부; 충전 모드 시 상기 충전부로부터 제공되는 교류 전력을 배터리를 충전 시키기 위한 직류 전력으로 변환하고, 운전 모드 시 상기 배터리로부터 제공되는 직류 전력을 3상 전동기를 구동시키기 위한 전력으로 변환하는 변환부; 상기 변환부가 상기 트랜스포머의 2차측과 상기 3상 전동기 중 하나와 선택적으로 폐회로를 형성하도록 스위칭되는 절환스위치를 적어도 하나 이상 포함하는 절환스위치부; 충전 모드 시 상기 트랜스포머의 2차측과 상기 변환부가 폐회로로 형성되고, 운전 모드 시 상기 3상 전동기와 상기 변환부가 폐회로로 형성되도록 상기 절환스위치의 스위칭을 제어하는 제어부를 포함하는 인버터-충전기 통합 장치가 제공될 수 있다.
