Based on the principle of fuel cell voltage changed with the work load voltage in the proton exchange membrane fuel cell (PEMFC) vehicle, A Buck DC-DC converter used by PEMFC were designed. The Buck DC-DC converter uses switch controller to control. The stability and anti—jamming performance of the converter were tested through the Matlab/simulink simulation. The results show that the designed Buck DC-DC converters can regulate voltage and maintain voltage stability very good.
