Implementation of Fuel Cell Emulation on DSPand dSPACE Controllers in the Design of Power Electronic Converters

The paper introduces a fuel cell (FC) emulator based on experimentally validated dynamic SOFC and PEMFC models for power electronics converter design and test, and fault diagnosis and mitigation. The fuel cell emulation developed includes both the steady state and transient responses of a fuel cell. A Matlab/Simulink environment is used to implement the FC model, convert and compile into C-program, build into real-time control, which is finally programmed into a dSPACE and/or DSP controller for prototype testing and design, and field testing. The output of the controller is sent to a linear power amplifier (power converter) that drives a power converter or a load. Experimental test was carried out to observe the steady state and transient responses of the FC emulator. Both implementation methods show very good results when compared with the experimental data.
