A soft start-up method for DC micro-grid based on improved two-level VSC with DC fault ride-through capability

Wen, Weijie (author), Lyu, Rui (author), Li, Botong (author), Cao, Hong (author), Yu, Jiali (author), Li, Bin (author), Popov, M. (author)

For the black start-up of DC micro-grids, three-phase charging resistors are required to limit the uncontrollable surge current. The main drawback of this start-up method is the difficulty in determining the appropriate resistance value to achieve a rapid start-up and limit the surge current with the change of grid parameters. To address this...
