DC/DC converter based on SiC semiconductors combined with online EIS detection functionality for Fuel Cell Electrical Vehicles
Résumé
This paper deals with the integration of Electrochemical Impedance Spectroscopy (EIS) functionality in DC/DC boost converter for Polymer Electrolyte Membrane Fuel Cell (PEMFC). A six-phase Interleaved Boost Converter (IBC) is chosen to extend the FC lifespan. Aiming at Fuel Cell Electrical Vehicles (FCEV) application, inverse coupled inductor and Silicon Carbide semiconductors are used to achieve low power losses, good thermal performance and highly-compacted system. Sliding Mode Control (SMC) has been chosen as the control strategy to satisfy the requirements of this non-linear system. EIS implementation is achieved by the injection of perturbation to the reference current of inductor and do not need any additional devices.
