OBC Common Mode charing coil

OBC stands for On-Board Charger EMC Common Coil , a device used in electric vehicles (EVs) to convert AC power from the grid into DC power that charges the EV's battery.

EMI stands for Electromagnetic Interference, which is a disturbance generated by an external source that affects an electrical circuit through electromagnetic induction, electrostatic coupling, or conduction.

A common mode Power Inductor coild, also known as a common mode choke inductor, is an electrical component that filters out common mode noise signals. It is often used in power supply applications to reduce EMI.

So, an OBC EMI common mode charging coil is High Current Inductor component used in an on-board charger to reduce electromagnetic interference during the charging process. This ensures the smooth operation of the charger and reduces the risk of damage to the EV's battery or electrical systems.
