摘要
主要介绍燃料电池发电系统中关键技术的研究现状。在分析质子交换膜燃料电池动静态特性的基础上,主要介绍燃料电池发电系统的结构拓扑以及常用电力电子变换器拓扑。进一步对现有的能量管理技术包括储能元件的接入以及控制策略的优势与不足分别做了总结。由于燃料电池输出低频纹波会降低其运行效率,并影响使用寿命,对三种常见低频纹波抑制方法:电容滤波法、阻抗插入法和有源滤波法,分析了其原理以及存在问题。最后对燃料电池发电系统研究现状做了总结并展望了其未来的发展趋势。
The status of power electronics for Fuel Cell （FC） was introduced mainly. Firstly, the static and dynamic characteristic of FC was introduced. Many architectures and topologies were discussed. Then power management technology including the interface of storage components and control strategy was analyzed in detail. The advantages and disadvantages were summarized. Besides, low frequency current ripple is harmful for FC, thus three normal low frequency current ripple reduction techniques were compared. Finally, the development trend of FC generation technology was put forward.
