Abstract / Description of output

In an offshore wind HVDC system, one option for connecting the variable speed wind turbine/permanent magnet generators to the DC grid is via passive rectifiers in series with DC/DC converters. This paper focuses on the DC/DC converters in the PMSG-rectifier-DC/DC converter the system. Three DC/DC converter topologies are investigated supplied by MW level PMSG wind generators. The topologies include the Phase Shift Full Bridge Converter, Series Load Resonant (SLR) Full Bridge Converter and Thyristor Based Resonant Converter. Detailed models of the DC/DC converters are built in the PLECS simulator. A 15kW (6kW) 150V/600V 500Hz Phase Shift full bridge DC/DC converter prototype has been built to validate the simulations.
