Abstract

In this paper, an optimized structure of the fuel cells (FCs) powered electric drive system is proposed. In this structure the supercapacitor is used to not only absorb the feedback energy of the motor but also store the unwanted output power of the FCs. So the power loss of the drive system will be reduced to minimum. The supercapacitor also is used to smooth the power output of the FCs. So the FCs can operate more efficiently. By proper control strategy the total efficiency of the drive system will be greatly improved. The system performance is simulated using MATLAB^®/SIMULINK and will be validated experimentally.
