Yoon-Jae Heo and Kyo-Beum Lee, "Islanded Operation Techniques in Distributed Power Using Dual-Active-Bridge Converters," Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, vol. 38, no. 4, pp. 317-323, Aug. 2024. > Paper

This paper proposes an islanded operation technique using DC-DC converters. The necessity of DC-DC converters and Dual-Active-Bridge converters in distributed power is analyzed. This paper shows soft-start and voltage control using Dual-Active-Bridge converters for stable operation in the DC grid. To validate the proposed algorithm, parameters are selected and a prototype is designed. The validity of the proposed islanded operation technique is demonstrated by the experimental results.
