摘要(Abstract)：

发展高压直流电网是解决电能大容量远距离传输及大规模可再生能源汇集的有效手段,高压大容量DC/DC变换器是实现不同电压等级的直流电网线路之间互联的关键设备,也是制约直流电网推广的主要技术瓶颈之一。然而已发表的研究工作主要集中于DC/DC变换器在中低压小功率应用,其在高压大容量场合的应用研究较少。为此,首先分析了高压直流电网对大容量DC/DC变换器的技术需求,然后系统回顾了高压大容量高增益DC/DC变换器拓扑的国内外研究现状,并总结了各类DC/DC变换器的特点及其在未来高压直流电网中的应用前景。在此基础上指出了高压直流电网用的大容量DC/DC变换器亟待研究的关键问题。所述内容为未来高压直流电网技术的研究和工程化应用提供了一定的技术参考。
