In this article, a reliability-based reconfiguration control method is proposed to improve the reliability indexes of proton exchange membrane fuel cells (PEMFC). The study introduces a three-stage interleaved boost converter and a passivity-based control approach that can adapt to high-temperature variations and load perturbations. The simulations based on Matlab/Simulink demonstrate the effectiveness of the proposed control scheme in enhancing the utilization of PEMFC power supplies in the presence of faults and perturbations.
The proton exchange membrane fuel cell (PEMFC) best exploitation needs to be based on reliability and fault tolerant control. One of the issues to fulfill this objective is ensuring high reliability indexes of the associated DC/DC converter, which is indispensable in practice. Three-stage interleaved boost converter is proposed in this context with a reliability-based reconfiguration control. The proposed control approach is passivity based, it is robust against high-temperature variations and load perturbations. However, this article proposes a novel method that adapts the reference current by a linear transformation. The fault tolerant control manages the open circuit failure to adapt the control algorithm to two-stage converter reconfigured structure. The matlab/simulink-based simulations show the effectiveness of the proposed control scheme as well as the reconfiguration method, which can give a technical improvement in the exploitation of PEMFC power supplies in the presence of faults and perturbations.
