Fuel cell electric vehicles (FCEVs) are seen as a promising solution for clean and sustainable transportation. The use of interleaved DC/DC Boost converter is required to regulate the low voltage generated by the fuel cell (FC) and to manage the energy flow. As weight and volume are a major constraint, the use of coupled inductors is a promising solution. However, implementing effective control for this particular architecture remains challenging. In this study, a novel approach to fault-tolerant robust control is presented. This method, based on the flatness and sliding mode control, incorporates an observer to accurately estimate input voltage and load current. A judicious optimization of the number of sensors is thus achieved, minimizing the cost and the probability of measurement errors. In addition, the integration of an open-circuit fault diagnosis algorithm enhances the system’s robustness in the face of faults. Simulation results in the Matlab/Simulink environment confirm the effectiveness of this approach. This significant contribution strengthens the reliability and robustness of DC/DC converters with coupled inductors and consolidate the position of the FCEVs as a promising sustainable mobility solution.
