On-Board Charger Application Overview


An OBC uses the AC current from a charging station or from household power to charge the batteries in Electric Vehicles (EVs) and Plug-In Hybrid Electric Vehicles (PHEVs). To charge the batteries from AC power, the OBC performs the Power Factor Correction (PFC) function followed by a DC-DC conversion to efficiently charge to the required voltage level for the battery.

With our combination of automotive-grade components for digital, analog, connectivity and power, we offer what you need to develop energy-efficient embedded control solutions for on-board charging.
