본 발명은 차량용 전력변환 시스템에 관한 것으로, 기준 이상 용량이 증가된 고용량의 고전압 배터리를 충전하기 위한 고용량 OBC(On Board Charger)부; 상기 고용량의 고전압 배터리의 고전압을 저전압으로 변환하여 저전압 배터리를 충전하기 위한 LDC(Low Voltage DC-DC Converter)부; 및 상기 고용량 OBC부와 LDC부를 통합 제어하는 OBC 및 LDC 통합 제어부;를 포함하며, 상기 OBC 및 LDC 통합 제어부는, ADC 동작과 PWM 스위칭 주파수 제어 동작의 동기(sync)를 맞추어 PWM(Pulse Width Modulation) 스위칭 제어를 수행한다.
A power converting system for a vehicle may include: a high-capacity on board charger (OBC) configured to charge a high-capacity high-voltage battery. a low voltage DC-DC converter (LDC) configured to convert a high voltage of the high-capacity high-voltage battery into a low voltage and charge a low voltage battery. The power converting system may further include an OBC and LDC integrated controller configured to perform integrated control of the high-capacity OBC and the LDC. The OBC and LDC integrated controller performs pulse width modulation (PWM) switching control by synchronizing ADC operation and PWM switching frequency control operation.
