燃料电池发电匹配网络设计方法研究

his paper focuses on the matching network theory and the design method for the fuel cell generations. 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 some typical characteristics of the circuit network, an idea that using switching mode network integration with duty cycle control to solve the fuel cell and load matching problem is presented. According to this idea, the synthesis method of the matching network to satisfy the requirements of dynamic and static characteristics fuel cell generation systems is explored, and four basic matching network structures and control methods are given in this paper. Finally, a 30kW fuel cell power generation prototype is designed and tested to verify the proposed matching network theory and design methods.
