EV DC/DC converters

Auxiliary DC/DC converters typically replace traditional alternator as a power source for all 12V or 24V accessories in electric vehicles. Bi-directional units can also be used to recharge high voltage traction battery from low voltage (12…24V) power source in case of emergency. Power DC/DC converters can transfer energy between traction system and energy source (such as battery, fuel cell, ultra-capacitor bank or mechanical generator) running at different voltage levels. All BRUSA converters are high performance bi-directional and liquid cooled. Choose the model below for more detailed description.
