资料介绍

针对质子交换膜燃料电池(PEMFC)和开关型负载的电路特性,分析了PEMFC经直流升压斩波(Boost)电路带开关型负载的电路系统的稳定性.通过使用PEMFC一阶RL等效电路模型和电感电流连续模式(CCM)下Boost电路的大信号平均模型,讨论了系统不稳定的原因,应用Matlab/Simulink针对不同开关型负载对Boost电路输出占空比的影响进行仿真,结果验证了分析的合理性.

In order to understand the electrical characteristics of Proton Exchange Membrane Fuel Cells(PEMFC) and switch-loads, the stability of such kind of system which is consisted in PEMFC ,Boost circuit, and switch -load is analyzed in this paper. To investigate the reason why the system is made unstable, the analytical model is made up of an one-order RL equivalent circuit for PEMFC and a large-signal mean model for Boost circuit in Continuous Conduction Mode(CCM). The software of Matlab is used for the simulation of the effect, which is caused by switch-loads, to the output duty circle of Boost circuit, and the validity of this analysis is demonstrated by the comparison of the simulation results.
