The energy conversion efficiency of fuel cell electric vehicle is high. However, the output characteristics of the current fuel cell tend to be weak and the output voltage fluctuation is apparent, so the DC/DC converter is used for voltage matching and transformation. Through the study on the characteristics of fuel cell in this paper, the main function and topology structure of the on-board DC/DC converter in fuel cell electric vehicle is introduced and the sliding mode control structure is

The simulation results show that, under the changes in input voltage and load, the fast response and stable output of the on-board DC/DC converter in fuel cell electric vehicle can be realized.
