Evaluation and Optimization of a Floating Interleaved DC-DC Boost Converter under Switch Fault for Fuel Cell Applications

Résumé

The durability of the dc-dc converter is one of the critical issues for the fuel cell power systems. To better exploit the converter and better choose the control scheme with switch fault consideration, the performance of the floating interleaved boost converter (FIBC) under switch fault are quantitatively evaluated firstly, based on two categories of control scheme. The evaluation is in terms of the components stress, the converter efficiency and the input current ripple. Secondly, to optimize the undesired high input current ripple caused by the switch fault, the phase shift angle reconfiguration is deduced to minimize the ripple. It is shown that this novel reconfiguration is different from that of the classical interleaved boost converter, due to the unequal duty cycles between phases. Both the deduced phase shift angle and the corresponding input current ripple are formulized explicitly, which is convenient for implementation. The evaluation results and the effectiveness of the proposed phase shift angle reconfiguration are finally validated by the simulations of Matlab/Simulink.
