摘　　要：论文着眼于燃料电池输出匹配网络理论与综合设计方法的研究。首先分析了燃料电池与负载的特性,并从静态和动态性能两个方面给出了匹配网络的要求。然后通过对几种典型电路网络的特性分析,提出了利用开关变换网络结合占空比控制设计以解决燃料电池与负载的匹配问题的思想。根据这一思路,从动态和静态特性要求出发探讨了匹配网络的综合设计,并给出了四种结构和几种控制方法。最后,采用30kW燃料电池发电装置的设计和试验,验证了文中所提出的理论和设计方法。The matching network theory and the design method for the fuel cell generations are focused.First,the characteristics of fuel cell and load are analyzed and the requirements of the matching networks considering the static and dynamic performance of the fuel cell power generations are given as well.After analysis of the characteristics of some typical circuit networks,the method of using switching mode network integrated with duty cycle control to solve the matching problem is proposed.According to the idea,the synthesis method of the matching network is explored and four basic matching network structures and control methods are given.Finally,a 30kW fuel cell power generation prototype is designed and tested to verify the proposed matching network theory and design methods.
