To control energy flow and optimise efficiency in HEV/EV powertrain subsystems such as Traction Inverters, OnBoard Chargers (OBC), DC-DC converters, and Battery Management Systems (BMS), precise and accurate current measurement is essential.
These high-voltage subsystems need to measure large currents at high common-mode voltages. For technical and regulatory reasons, the current measurements require isolation as well as very high performance in harsh automotive environments
