Experimental validation of high-voltage-ratio low-input-current-ripple DC-DC converters for fuel cell applications

This work describes the practical implementation of a Floating-Interleaving Boost Converter (FIBC) for fuel cell applications. The paper aims to validate the concept of digitally-controlled from four-phases-FIBC for fuel cell applications. FIBC exhibits interesting performance in terms of magnetics, input, and output current ripple, part count and distributed power losses. A potential field of application is indeed medium and higher power fuel cell front-end converters, where minimizing input current ripple is significant but also redundancy and reliability are crucial. Actually, this approach covers all these aspects since provide module and device redundancy with real-time and flexible digital control reconfiguration. Relevant aspects related to design; modeling, simulation and experimental verification of 100W, Arduinocontrolled, 4-phases-FIBC are treated in this paper.
