Comparing shunt- and Hall-based current-sensing solutions in onboard chargers and DC/DC converters

Electric vehicles (EVs) and hybrid electric vehicles (HEVs) offer higher fuel-efficiency and lower emissions compared to gasoline or diesel vehicles. To control energy flow and optimize efficiency in HEV/EV subsystems such as onboard chargers (OBC), traction inverters, DC/DC converters, and battery management systems (BMS), accurate current measurements at high common-mode voltages are essential.
