Design and control of a 6-phase Interleaved Boost Converter based on SiC semiconductors with EIS functionality for Fuel Cell Electric Vehicle

Abstract : The objective of this thesis work is devoted to the design and control of a DC/DC boost converter for Fuel Cell Electric Vehicle (FCEV) application. A 6-phase Interleaved Boost Converter (IBC) based on Silicon Carbide (SiC) semiconductors and inversed coupled inductors of cyclic cascade structure is proposed. The input current ripple is reduced significantly and the lifespan of Polymer Electrolyte Membrane Fuel Cell (PEMFC) can be extended. Low power losses, good thermal performance and high switching frequency have been gained by the selected SiC-based semiconductors. The volumes of passive components (inductors and capacitors) are reduced. Thanks to the inverse coupled inductors, the core losses and copper losses are decreased and the compact magnetic component is achieved.Sliding-Mode Control (SMC) strategy is developed due to its high robust to parameter variations. on-line Electrochemical Impedance Spectroscopy (EIS) detection functionality is successfully integrated with SMC. No additional equipment and sensor is required.The real-time Hardwar In the Loop (HIL) validation of the proposed converter is achieved by implement the power part into the FPGA and the control into the microprocessor in the MicroLabBox prototyping system from dSPACE. The comparison between off-line simulation and HIL validation demonstrated the dynamic behavior of the proposed converter and validated the implementation of the control into a real time controller before future tests on experimental test bench.
