Abstract

nowadays, many researches for plug-in hybrid electric vehicles have been actively carried out to improve the gas mileage in comparison with mass-produced hybrid electric vehicles. In this paper, the on-board charger for plug-in hybrid electric vehicles is studied for obtaining the high efficiency. The on-board charger consists of two phase interleaved PFC circuit and LLC resonant converter. The new design procedures of LLC resonant converter are proposed in this paper. These are very simple and powerful method. In order to verify the abovementioned contents, the LLC resonant converter is designed and tested by using PSIM tool.

최근 양산되고 있는 하이브리드 전기자동차에 비해서 연비를 좀 더 개선하기 위한 플러그인 하이브리드 전기자동차(Plug-in Hybrid Electric Vehicle)에 대한 연구가 활발히 진행되고 있다. 이 논문에서는 플러그인 하이브리드 전기자동차를 위한 고효율의 탑재형 충전기(on-board charger)에 대해서 연구한다. 탑재형 충전기는 2상 인터리브드 PFC 회로와 LLC 공진형 컨버터로 구성된다. LLC 공진형 컨버터의 새로운 설계절차를 본 논문에서 제안한다. 이는 매우 쉽고 강력한 방법이다. 위에서 언급한 내용을 확인하기 위해서 LLC 공진형 컨버터를 설계하고 PSIM 툴을 이용하여 테스트한다.
