Onboard battery charger

Onboard battery chargers (OBC) are critical components in electric vehicles that convert external AC power to DC for battery charging. These high-voltage power conversion circuits are vulnerable to transient surges from unstable grids, electrostatic discharge during plug-in/out operations, and conducted or radiated electromagnetic interference along harnesses. YINT Electronics’ OBC protection solution integrates high-power TVS transient suppressors for fast overvoltage clamping, gas discharge tubes (GDT) for high-energy surge diversion, ESD protection arrays for sensitive signal lines, and common-mode EMI filters to reduce conducted noise — ensuring robust protection, improved charging reliability and extended system lifetime in EV charging environments.
