Analysis on some Key Problems of High Power DCDC Converter for Fuel Cell Electrical Bus

Abstract:

The significance of researching on fuel cell electrical vehicle (FCEV) DC/DC converter, FCEV driving system structure and requirement with DC/DC converter are introduced firstly. Some key problems of development in FCEV DC/DC converter are particularly analyzed, including of reliability, efficiency, static and dynamic characteristic, etc. The average efficiency of boost or buck circuit can reach more than 95%. The dynamic response time of DC/DC converter is below 160 ms. All kinds of DC/DC converters operate with zero error, and various technical indicators can satisfy the operating requirement. The converters are successfully used in china fuel cell city buses and technical indexes are fulfilled.
