FPGA-based Real-Time Simulation of Floating Interleaved Boost Converter for FCEV Powertrain

Floating interleaved boost converter (FIBC) is a high-voltage-ratio DC/DC converter with low input current ripple which is suitable for the fuel cell electric vehicle (FCEV) powertrain. This paper proposed a methodology for the FPGA-based real-time simulation of FIBC converter with a time-step of 25 ns. The FIBC is modeled with highly paralleled structure and division-free characteristic to accelerate the simulation on FPGA. The accuracy and effectivity of proposed methodology are verified by the offline simulations and the practical experiments.
