Power converter design for a fuel cell electric vehicle

This research is developed the electric vehicle by the fuel cell. Between fuel cell source and motor controller, we add new power converter, offer steady output voltage to motor controller and drive the direct current hub motor. Converter not only offers steady output voltage but it also combines with coupling inductance technology to battery charger. Besides offers energy to drive motor, and fuel cell charges battery. Micro controller will read the working state of the fuel cell, transmitted by UART interface and show the voltage, current, temperature, gas pressure of the fuel cell in LCD display, reach the function of immediately control the state of electric power system. Verifing via the experiment, the fuel cell electric vehicle that this thesis claimed, even if the fuel cell model in load changing case, the electric converter still can reach the steady output voltage to drive direct current hub motor.
