| Abstract: | Large-scale and long-distance offshore wind power is the trend of future wind power generation with abundant offshore wind energy resources. As the core equipment of wind power DC collection system, the research of high voltage and high power DC/DC converter is particularly important. Most of the existing DC/DC converters are used in low/medium voltage and low power applications. The technical requirements of offshore wind power DC/DC converters were introduced firstly in this article. Then the modular combination DC/DC converter topology, sub-topology structure, control strategy, modeling method suitable for offshore wind power were presented. Finally, the content of the modular combination DC/DC converter to be further studied was summarized and analyzed, which provides a reference for its application in offshore wind power DC collection. |
