摘要
单体燃料电池电压偏低且稳定性差,很难直接驱动负载工作,且燃料电池单独工作时存在冷启动慢、动态响应能力差、不支持能量的双向流动等一些问题,该文针对这些问题,结合超级电容辅助能源装置,研究变换器的拓扑结构及其控制方法,提出一种燃料电池用三端口双向变换装置。通过单个多端口变换器装置实现多能源与负载间协调控制,实验结果表明所提变换器系统与传统的基于直流母线的变换系统相比能够有效抑制低频电流纹波,具有结构简单、能量转换级数较少、转换效率较高的优点。
It is difficult to directly drive the load for the single fuel cell voltage is low and the stability is poor,and there are some problems such as cold start and slow,dynamic response ability,and no two-way flow of energy.In view of these problems,A Multi-port converter for fuel cell is proposed based on the supercapacitor.The experimental results show that the proposed converter system can effectively suppress the low-frequency current ripple,the advantages of simple structure,low energy conversion series and high conversion efficiency,Compared with the traditional DC-DC converter.
