This paper deals with the integration of the electric power-conditioning interface to the Fuel Cell (FC) module for embedded electric power generation. Specifically, the current study aims to propose an adequate control strategy to achieve a high efficiency of a compact 20kW DC/DC PEMFC output multiphase converter based on new wide-bandgap technology devices. The proposed control strategy is based on the part-load approach fulfilling demanding specifications such as low input current ripple, high performances of the converter over the load power range and small losses enabling the simplification of the cooling circuit.
