The Converter Box (CBX154) of BRUSA includes the functions of several devices in an extremely compact housing. It allows for the first time to couple fuel cell, HV battery and electric motor with only one box. The converter box comprises a HV battery converter and a fuel cell converter. The fuel cell converter is a unidirectional DC/DC converter with high efficiency. It boosts the output voltage of the fuel cell to the DC link voltage. The HV battery converter is a bidirectional DC/DC converter with high efficiency. It boosts the output voltage of the HV battery also to the DC link voltage. The main function of the battery converter is to balance the energy differences between the delivered (fuel cell) and required (drivetrain) power by charging or discharging the HV battery. The HV battery basically works as an energy buffer.
The Converter Box is at the A-sample stage
