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.

Demonstration Applications for OBCs
11 kW Dual Active Bridge DC-DC Demonstration Application
Featuring dsPIC® Digital Signal Controllers (DSCs) and silicon carbide (SiC) MOSFETs, this demonstration platform is part of an On-Board Charger (OBC) used for charging Electric Vehicles (EVs). This system also includes an 8-bit MCU, gate drivers, a buck regulator, a Switch Mode Power Supply (SMPS) controller, push-pull PWM controller, CAN FD transceiver and LDO. The highly modular and configurable hardware with Plug-in-Modules (PIMs) and flexible software supports different modes of operation.
