Abstract

This paper describes the performance of DC-DC converters for buoy such as buck, boost, and buck-boost. The operating characteristic and charging efficiency with battery, which has a considerable properties about converters with PV(photovoltaic) system, is analyzed in this paper. It is performed by using the MPPT(Maximum Power Point Tracker) algorithm The basic equations of switching operation for converter are described, and the equations are analyzed with according to switch state. Whereas this analysis is directed toward the selection of converter for buoy, it also provides the insight into the behaviour of converter and performance of the proposed algorithm Finally, the suitable DC-DC converter is proposed for buoy, and the characteristic experiment is performed with the buck converter.

본 논문은 벅, 부스터, 벅-부스트 등의 부이용 DC-DC 컨버터 성능에 대하여 기술하였다. PV 시스템과 연계한 컨버터에 관한 특성이 고려된 동작특성 및 충전효율에 대하여 분석하였다. 그것은 MPPT 알고리즘과 더불어 수행되었다. 컨버터를 위한 기본 스위칭 방정식을 기술하고, 스위칭 상태에 따른 방정식을 해석하였다. 이 해석은 부이선택에 초점을 맞추고 있으며, 또한 컨버터 동작 및 제안한 알고리즘의 성능을 관찰하였다. 마지막으로 부이에 적합한 DC-DC 컨버터를 제안하였으며, 벅 컨버터에 대한 특성실험도 수행하였다.
