EV Charging

Power Electronics at the Pump

With the decarbonization of automobiles and other transportation vehicles, there will be an increasing need for vehicle charging infrastructure. Robust devices and systems, designed for safety and reliability, are needed to power the cars of the future.

ON Semiconductor’s super-junction MOSFETs, IGBTs, SiC devices, and power integrated modules (PIMs), along with our gate drivers, sensing, control and peripheral power products provide a complete system solution for electric vehicle charging systems of all types and power levels.

EV Charging equipment is normally classified from Level 1 to Level 4, corresponding to the charging power level, as described below. For Level 1 and Level 2 charging, the main power electronics are normally inside the vehicle. ON Semiconductor technology for On-Board Chargers (OBCs) can be found in the Vehicle Electrification solution pages.

Charging Levels

In Level 3 and 4 EV Charging equipment, the higher power, cost and weight of the AC to DC conversion equipment requires fixed installations. Below is a block diagram for an EV Charging station, with a Vienna rectifier for the PFC front end and a full bridge resonant LLC DC-DC stage. The green blocks show all the subsystem solutions which are offered by ON Semiconductor.
