차량용 컨버터에 관한 기술이 개시된다. 본 발명의 일 실시예에 따른 차량 ACC 전류 제한 회로는, 차량의 ACC 모드에서 ACC 전류를 출력하는 차량용 컨버터에 설치되는 회로로서, 상기 컨버터의 전압 변환 회로에서 출력되는 ACC 전류가 통과되도록 배치되는 제1 저항기; 상기 ACC 전류의 크기가 소정 임계치 이하인 경우 턴 온(turn on)되어 상기 제1 저항기를 통과한 전류를 상기 컨버터의 ACC 출력 단자로 전달하고, 상기 ACC 전류의 크기가 상기 임계치보다 큰 경우 턴 오프(turn off)되는 제1 스위치 소자; 및 상기 ACC 전류의 크기가 상기 임계치 이하인 경우 턴 오프되고, 상기 ACC 전류의 크기가 상기 임계치보다 큰 경우 턴 온되어 상기 ACC 전류를 접지 측에 전달하는 제2 스위치 소자를 포함하여, 차량의 ACC 전원을 사용하는 액세서리 기기들을 추가적인 장치 없이 안전하게 보호함은 물론, ACC 부하에서 요구하는 전력이 큰 경우에도 충분한 출력 전압을 제공하면서 차량용 컨버터의 제조 비용을 절감한다.
Disclosed is technology related to a converter for a vehicle. According to an embodiment of the present invention, a circuit for limiting an ACC current of a vehicle is installed on a converter for a vehicle for outputting an ACC current in an ACC mode of the vehicle, and comprises: a first resistor arranged to allow an ACC current output by a voltage conversion circuit of the converter to flow therethrough; a first switch element turned on to transfer a current flowing through the first resistor to an ACC output terminal of the converter if the level of the ACC current is lower than or equal to a prescribed threshold, and turned off if the level of the ACC current is larger than the threshold; and a second switch element turned off if the level of the ACC current is lower than or equal to the threshold, and turned on to transfer the ACC current to the ground if the level of the ACC current is larger than the threshold. Accessory devices using ACC power of a vehicle are safely protected without an additional device. Even if power required by an ACC load is large, a sufficient output voltage is provided, and manufacturing costs of a converter for a vehicle are reduced.
