Abstract

In this paper, a hybrid power system supplied by a fuel cell and a lead-acid battery is realized by using the digital signal processor (DSP) TMS320LF2407 for power management and interleaved control. When the power provided from the fuel cell is higher than the load power, the extra energy may be used to charge the lead-acid battery. When the fuel cell can not provide enough energy to the load, the shortage of energy will be supplied by the lead-acid battery. Experimental results show that the system operating modes can be changed automatically, and that the output voltage is regulated well during load variations. Also, high system efficiency is achieved.
