Abstract

The interest is coming to be high, recently with depletion of the fossil fuel and with carbon dioxide exhaust limit about emittion, from a car of Internal combustion engine to Electric vehicle. AC-DC converter is necessary to battery charging which is an electric vehicle energy storage. Necessary conditions of the converter are necessary for wide output voltage range, high efficiency, high power factor etc. It is composed two stages for wide output voltage range and insulation. Preliminary stage uses LLC resonant converter and the after stage uses BOOST converter PFC circuit for being considered a power factor and confirmed experimentally.

최근 화석 연료의 고갈과 이산화탄소 배출 제한으로 인하여 내연기관 자동차에서 전기 자동차로의 대한 관심이 높아지고 있다. 전기 자동차 에너지 저장 요소인 배터리 충전에 필요한 AC-DC 컨버터가 필요하며 컨버터의 필요조건 으로 넓은 출력 전압 범위, 고효율, 높은 역률 등을 들수 있다. 넓은 전압 범위와 절연을 위해 2단 구성 하였다. 앞단은 LLC 컨버터를 후단은 역률을 고려 하여 BOOST 컨버터를 이용한 PFC 회로를 구현하여 실험적으로 확인 하였다.
