燃料电池蓄电池混合供电系统

Fuel Cell and Battery Hybrid Power Supply System

燃料电池是一种清洁、环保的可替代能源,但昂贵的价格限制了其推广。本文结合燃料电池、蓄电池的优点,提出燃料电池与蓄电池混合供电方式,降低系统成本。为了减小输入电流纹波延长电池使用寿命,变换器均采取交错并联拓扑。文中详细分析了系统工作原理及其控制方式,仿真结果验证了系统设计方案的可行性。

Fuel cell is an eco-friendly energy source for human, but expensive cost is unacceptable at present, this paper proposes a new idea, combined with storage battery and fuel cell, to reduce the cost of the battery. On the other hand, fuel cell is a power station, it can charge battery when battery is depletion, in order to minish input current ripple, interleaved converter has been taken, and this can extend fuel cell＇s life. Finally, every state of system has been analyzed in its control method and working theory, the simulation result shows the feasibility of the design.
