In this paper, an innovative control strategy for hybrid power source dedicated to automotive applications is detailed. Firstly, an analysis of classical hybrid architectures using FC / SCs is presented. Then, an analysis of load requirements for automotive applications is proposed. A new control strategy of a single converter, based on cascaded control loop with a decoupling strategy in the frequency domain, is fully explained. Finally, experimental results on a Ballard PEMFC are presented to illustrate the effectiveness of the proposed method.
