Abstract :
Since a fuel cell system has a low voltage output, it requires a boost DC/DC converter for the most of vehicle and stationary power applications. In this paper, a robust sliding mode controller for the current fed full bridge DC/DC converter for PEM fuel cell systems is presented. The details of the sliding mode controller for the converter are derived and designed with a dynamic PEMFC model. The proposed sliding mode controller for converter with the PEMFC model is tested through Matlab/Simulink simulation. The results show the robust dynamics of the sliding mode controller with respect to load changes and the fuel cell voltage variation.
