Abstract

This paper proposes a design and experiment of three phase interleaved dc-dc converter for 5kW battery charger. The charger consists of a three-phase interleaved dc-dc converter, which interfaces batteries and DC link, and a grid connected inverter. Lead-acid battery is modeled in a simple R-C model by matlab. Parameters of the battery are estimated based on step current discharging test. The battery is connected to three-phase interleaved DC-DC converter in order to reduce the ripple current to the battery and so, increase the lifetime of battery. Controller for charging and discharging mode is designed and tested in a 5kW charger prototype.

본 논문은 5kW 배터리 충전기용 3상 인터리브드 DC-DC 컨버터 설계 및 실험에 대하여 서술하였으며, 배터리 시스템은 풍력 시스템의 안정화를 위해 사용한다. 배터리 충전기는 배터리, 3상 인터리브드 양방향 DC-DC 컨버터, 직류단, 계통연계형 인버터로 구성된다. 납축전지는 matlab으로 간단한 R-C모델링 하였으며, 스텝 전류 방전 실험에 따라 배터리 파라미터를 구하였다. 3상 인터리브드 DC-DC 컨버터를 이용해 배터리의 전류 리플을 감소시켰으며, 5kW 배터리 충전기를 제작하여 충·방전모드 제어기를 설계하고 실험하였다.
