본 발명은 차량의 전압 변환 시스템 및 전압 변환 방법에 관한 것으로, 시동 감지 정보 및 전압 공급 정보에 기초하여 스위치 제어 정보를 생성하는 전압 변환 제어부, 고전압 배터리의 전압 레벨과 DC-link 커패시터의 전압 레벨을 비교하여 상기 전압 공급 정보를 생성하는 배터리 관리부, 및 상기 스위치 제어 정보에 기초하여 저전압 전기 에너지를 고전압 전기 에너지로 변환하거나 상기 고전압 전기 에너지를 상기 저전압 전기 에너지로 변환하는 전압 변환부를 포함할 수 있다.

    The present invention relates to a voltage conversion system of a vehicle and a voltage conversion method. The voltage conversion system of the vehicle of the present invention comprises: a voltage conversion control unit generating switch control information based on start-up detection information and voltage supply information; a battery management unit generating the voltage supply information by comparing a voltage level of a high voltage battery with a voltage level of a DC-link capacitor; and a voltage conversion unit converting a low voltage electrical energy into a high voltage electrical energy or converting the high voltage electrical energy into the low voltage electrical energy based on the switch control information. The voltage conversion system of the vehicle is capable of converting a high voltage to a low voltage or converting the low voltage to the high voltage.
