A designing method of the power source specifications for hybrid powered traction systems with fuel cells and EDLCs

This paper provides designing methods of the power source capability and appropriate circuit configurations to save the output power of fuel cells(FCs) and the capacitance of electric double layer capacitors(EDLCs). Especially, a method to determine the specifications of the FCs and the EDLCs are discussed utilizing double DC/DC converters. The designed results are verified by numerical simulations.
