Abstract
Fuel cell hybrid vehicles use an electric energy storage system such as a battery that can provide additional traction power. This is needed to improve vehicle operation during acceleration and to avoid dynamic current stress of the fuel cell stack. The battery is used for regenerative braking and is connected to the DC-bus of the drive train via a bidirectional DC-DC converter. This paper investigates non-isolated hard-switched bidirectional DC-DC converters with voltage and current ratings which are common in fuel cell hybrid vehicles. The focus is on the comparative analysis of converters regarding the current and voltage stress as well as on the passive component design. Furthermore, a general evaluation for the use in fuel cell hybrid vehicles is discussed.
