This paper proposes an islanded operation technique using DC-DC converters. When the AC grid blackouts within the DC grid, the islanded operation technique becomes essential. Voltage control is necessary according to the islanded operation technique of DC-DC converters. This paper shows soft-start and voltage control using Dual-active-bridge converters for stable operation in the DC grid. The validity of the proposed islanded operation technique is demonstrated by the experimental results.
