The study of bidirectional DC-DC converter in the DC microgrid [PDF]
作为新能源的有效利用方式之一的直流微电网没有无功功率的损耗,不需要跟踪频率和相位,可靠性和可控性有较大程度的提高,更适合分布式能源的接入和应用。双向DC-DC变换器承担着母线与储能之间能量双向流动的重要作用。同时,它还可以作为直流微电网之间的互联元件,具有十分重要的研究价值。 本文针对全桥拓扑结构的双向DC-DC变换器展开较为深入的研究。 首先,详细分析了在移相控制方式下,双向DC-DC变换器的在降压方向和升压方向的工作原理及零电压开关(ZVS,Zerovoltageswitching)的具体过程 ...
