본 발명의 차량 배터리 출력 시스템은 차량 배터리의 직류 전류를 공급받아서 다른 직류 전류로 변환하는 DC-DC 컨버터; 상기 DC-DC 컨버터에서 변환된 차량 배터리의 직류 전류를 교류 전류로 변환하는 DC-AC 인버터; 입력 전류(Iin), 입력 전압(Vin), 출력 전압(Vout) 및 출력 전류(Iout)를 입력받아 스위칭 주파수 변조지수(m)을 산출하여 상기 DC-DC 컨버터를 제어하기 위한 제어 신호를 생성하는 컨트롤러; 및 상기 DC-DC 컨버터와 상기 DC-AC 인버터사이에 배치되고 커패시터를 포함하는 DC 링크부를 포함한다.
A vehicle battery output system includes: a DC-DC (direct current-direct current) converter configured to receive a direct current from a vehicle battery and convert the direct current into another direct current; a DC-AC (direct current-alternating current) inverter configured to convert the another direct current of the vehicle battery, converted by the DC-DC converter, into an alternating current; a controller configured to receive an input current, an output voltage, and a reference voltage and calculate a switching frequency modulation index to generate a control signal for controlling the DC-DC converter; and a DC (direct current) link disposed between the DC-DC converter and the DC-AC inverter and including a capacitor.
