ePower

14175c DC/DC Converter
The DC/DC converter supplies 12 V auxiliaries for Hybrid or
Electrical Vehicles from its HV battery.
The architecture is based on modular design blocks, making
it scalable to cover a wider range of power outputs. With its
origin in passenger vehicles, great effort has been put into
minimizing packaging volume and weight. The robust
design of the 14175c DC/DC Converter meets high safety and
reliability requirements, with a superior power density.
