An On-Board Charger (OBC) is a crucial component in electric
(EV) and plug-in hybrid vehicles (PHEVs). It converts AC power
from the grid into regulated DC power to charge the vehicle’s
battery safely and efficiently.
To meet the increasing demands for higher power density, efficiency, and reliability in compact designs, Premo provides a range of advanced electromagnetic components tailored for OBC applications.
