| 摘要: |
| 为了弥补燃料电池作为独立备用电源存在的不足，提出一种以燃料电池为主电源、蓄电池为辅助电源的备用电源系统。根据燃料电池备用电源系统特性，提出了系统电压阈值补偿控制策略及蓄电池充放电控制策略，实现备用电源的不间断切换及动态补偿。基于提出的系统结构和控制策略，研发了一台3 kW燃料电池备用电源样机系统。实际测试表明，所提的系统结构及控制策略实用、有效，所设计的燃料电池备用电源系统可用作不间断备用电源。 |

| Abstract: |
| Since fuel cell has some disadvantages as independent backup power system，a kind of backup power system is proposed，which takes fuel cells as its primary source and batteries as its auxiliary source. According to the characteristics of fuel cell backup power system，a strategy of system voltage threshold compensation control and battery charge／discharge control is proposed to implement the uninterrupted switching and dynamic compensation. A 3 kW prototype is developed and the experimental results demonstrate that，the proposed system structure and control strategy are practical and effective and the designed system can be safely used as uninterruptible backup power. |
| Key words: fuel cells backup power voltage threshold control uninterrupted switching compensation |
