摘　　要：海上风能资源丰富,大规模远距离的海上风电是未来风力发电的趋势。作为风电直流汇集传输的核心设备,适用于高压大功率的DC/DC变换器研究尤为重要。已有的DC/DC变换器大多工作于中低压小功率环境,为此文章介绍了海上风电DC/DC变换器的技术需求,详述了适用于海上风电直流汇集的模块组合式DC/DC变换器拓扑结构、子拓扑结构、控制策略,总结分析了模块组合式DC/DC变换器需进一步研究的内容,为其应用于海上风电直流汇集提供了参考。Large-scale and long-distance offshore wind power is the future trend of wind power generation with abundant offshore wind energy resources.As the core equipment of wind power DC collection,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.On this basis,the technical requirements of offshore wind power DC/DC converters are introduced in this paper.The topology,sub-topology structure and control strategy of modular combination DC/DC converter suitable for offshore wind power DC collection are presented.The content of the modular combination DC/DC converter to be further studied is summarized and analyzed,which provides a reference for its application in offshore wind power DC collection.
