Résumé

Hydrogen fuel cells are emerging as a key technology for a greener and more sustainable future. The paper explores a multi-stack hydrogen fuel cell system applied on a maritime transport (1 kV, 1 MW). The study addresses two main challenges: the high power demand of the heavy-duty transport and the efficient management of the power supplied by the sources. To meet these requirements, the proposed architecture is based on a parallel configuration of three-level boost converter. The results obtained from this simplified approach are then compared to those derived from an instantaneous model incorporating pulse-width modulation. The results validate the average modeling approach, which offers significantly faster simulations and proves useful for control law design.
