A NOVEL MULTIDEVICE INTERLEAVED BOOST CONVERTER FOR FUEL CELL HYBRID ELECTRIC VEHICLES

Multiphase converter topologies for use in high performance applications have received increasing interest in recent years. This paper proposes a novel multidevice interleaved boost converter ( MDIBC ) that interfaces the fuel cell with the powertrain of hybrid electric vehicles. In this research, a multidevice converter with interleaved control is proposed to reduce the input current ripples, the output voltage ripples, and the size of passive components with high efficiency compared with the other topologies. In addition, low EMI and low stress in the switches are expected. The proposed dc/dc converter is compared to other converter topologies such as conventional boost converter (BC) , multidevice boost converter (MDBC), and two-phase interleaved boost (IBC) to verify its dynamic performance. The dc/dc converter topologies and their controller are designed and investigated by using MATLAB/Simulink. The simulation results have demonstrated that the proposed converter is more efficient than other dc/dc converter topologies in achieving high performance and reliability for high-power dc/dc converters.
