N2 - Offshore medium-voltage DC (MVDC) wind farm layout can bring many advantages compared to the conventional AC system. The series-connected MVDC system could be implemented using three-phase dual-active-bridge (DAB3) converters with phase-shift modulation. For each wind turbine, a modular system is proposed in this paper where several dual-active-bridge converters are connected in an input-parallel output-series (IPOS) configuration to increase the voltage level of the controlled-rectifier. The DC link output of each wind turbine is the series-connected 3DAB outputs. Moreover, the DC links of several wind turbines are also connected in a series to form the MVDC link. A design procedure for the proposed system is presented. The control of the whole system is discussed including the machine-side, the grid-side, and the DAB3 converter control. The main advantage of the proposed system is the modularity and reduced amount of the required cabling compared to previous systems. Simulation results are presented to verify the proposed DC wind farm at different operating conditions.
