Abstract :
Fuel cell engine cannot provide enough power at cold start. According to these, a 5 KW isolated boost full bridge (IBFB) converter is developed as the auxiliary power supply. With the IBFB converter, the 24 V DC of the auxiliary storage cell of the fuel cell electric vehicle (FCEV) is converted to a stabilized 300 V high DC. The IBFB converter is controlled with a double voltage and current loop based on DSP- TMS320LF2407. Experimental results show that the system has excellent properties and can be used in areas like FCEV
