DC-DC converters convert HV to 48V, HV to 12V, and 48V to 12V in the various configurations of electric vehicles. The key design requirements for DC-DC converters are low losses, high efficiency, low volume and light weight. There are many architectures requiring different kinds of semiconductor devices.
48V to 12V DC/DC converter
In mild hybrid electric vehicles, the DC/DC converter is a mandatory part of the overall system. It is typically used in buck mode to supply electrical energy to the 12V system, which has been created by the 48V starter generator. In some cases, such

HV to LV DC/DC converter
Electric vehicles (EVs) use two power systems: a high-voltage battery pack, typically 400 to 800 VDC, for traction, and a low-voltage system, usually 12 V or 48 V, for the vehicle’s electrical accessories. Traditionally, the low-voltage battery was c
