摘要
燃料电池发电因其高效环保越来越受到社会各界的关注,但其输出电压范围宽、特性偏软,必须借助于大功率DC/DC变换器作为输出功率调节环节。通过分析燃料电池发电系统中的功率分配原理,引入蓄电池二阶RC等效电路,从输出功率的角度对调节器进行建模并设计了相应的控制器,通过在Matlab中仿真和制作样机试验,均取得了良好的效果,结果证明了设计的合理性。
The fuel cell power generation is widely concerned by the community for its high efficiency and environmental friendly. But its output is soft and in wide range, so a high power DC/DC converter is necessary to be used as the power regula- tor. The power distribution in the cell power generation system was analyzed and the regulator model was established with battery 2nd RC model, and the corresponding controller was designed at the same time. Matlab simulation and experimental prototype achieved good effects. The results prove the design be rational.
