The present invention relates to a driving circuit for an electric vehicle having a battery pack and an inverter, and a control method therefor. A driving circuit according to an embodiment of the present invention comprises: a first contactor connected between a first terminal of the battery pack and a first terminal of a capacitor included in the inverter; a second contactor and a current limiting circuit which are connected in parallel to the first contactor; and a control unit for controlling the operation of the first contactor and the second contactor. The second contactor and the current limiting circuit are connected in series with each other, and the current limiting circuit includes at least one resistance. The control unit outputs a first control signal while the first contactor is operating normally and outputs a second control signal while the first contactor is operating abnormally. The first control signal induces a turn-on of the first contactor, and the second control signal induces a turn-on of the second contactor.

    La présente invention concerne un circuit d'entraînement pour un véhicule électrique comportant un bloc-batterie et un onduleur, ainsi qu'un procédé de commande associé. Un circuit d'entraînement selon un mode de réalisation de la présente invention comprend : un premier contacteur connecté entre une première borne du bloc-batterie et une première borne d'un condensateur inclus dans l'onduleur ; un second contacteur et un circuit de limitation de courant qui sont connectés en parallèle au premier contacteur ; et une unité de commande pour commander le fonctionnement du premier contacteur et du second contacteur. Le second contacteur et le circuit de limitation de courant sont connectés en série l'un à l'autre, et le circuit de limitation de courant comprend au moins une résistance. L'unité de commande émet un premier signal de commande tandis que le premier contacteur fonctionne normalement et émet un second signal de commande tandis que le premier contacteur ne fonctionne pas normalement. Le premier signal de commande induit une mise en marche du premier contacteur, et le second signal de commande induit une mise en marche du second contacteur.

    본 발명은 배터리 팩과 인버터를 구비하는 전기 자동차용 구동 회로 및 그것의 제어 방법에 관한 것이다. 본 발명의 일 실시예에 따른 구동 회로는, 상기 배터리 팩의 제1 단자와 상기 인버터에 포함된 커패시터의 제1 단자 사이에 연결되는 제1 컨택터; 상기 제1 컨택터에 병렬 연결되는 제2 컨택터와 전류 제한 회로; 및 상기 제1 컨택터 및 상기 제2 컨택터의 동작을 제어하는 제어부;를 포함한다. 상기 제2 컨택터와 상기 전류 제한 회로는 상호 직렬 연결되고, 상기 전류 제한 회로는 적어도 하나의 저항을 포함한다. 상기 제어부는, 상기 제1 컨택터가 정상적으로 동작하고 있는 동안에는 제1 제어신호를 출력하고, 상기 제1 컨택터의 비정상으로 동작하고 있는 동안에는 제2 제어신호를 출력한다. 상기 제1 제어신호는 상기 제1 컨택터의 턴온을 유도하고, 상기 제2 제어신호는 상기 제2 컨택터의 턴온을 유도하는 것이다.
