High step-up DC/DC converter for fuel cell hybrid electric vehicles

Abstract

This paper presents a high step-up converter with fuel cell for hybrid electric vehicle power supplies. The fuel cell has the power characteristics of low voltage and high current due to electrochemical characteristic. Thus, a high step-up dc-dc converter is devised for boosting the fuel cell voltage to be a constant dc-bus voltage. The high step-up dc-dc… (More)
