Analysis, comparison and selection of DC-DC converters for a novel modular energy conversion scheme for DC offshore wind farms

Offshore wind farms provide benefits over onshore farms in terms of the amount of generated energy and environmental impact. Cost efficient energy transmission is one of the challenges of such installations. In this context, direct connection of DC wind turbines to the transmission line is a promising solution. This paper proposes a novel energy conversion scheme for the direct connection of the DC wind turbines to the transmission line. In addition, a brief comparison between two DC-DC converters is presented to establish the most suitable topology for the modular DC-DC converter required by the proposed energy conversion scheme.
