EV Charging Solutions from ON Semiconductor

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.

ON Semiconductor is a member of CharIN e.V., an industry consortium to develop and promote the CCS standard for electric vehicle charging.

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.

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.

Products Descriptions
IGBTs Insulated gate bipolar transistors (IGBTs) for electronic ignition, flash, motor drive, and other high current switching applications.
Rectifiers Standard and fast recovery rectifiers.
Silicon Carbide (SiC) Diodes Silicon Carbide Schottky Diodes
MOSFET/IGBT Drivers MOSFET drivers and IGBT drivers for low side, high side, and half-bridge drive circuits.
IGBT/MOSFET Gate Drivers Optocouplers

The IGBT/MOSFET gate drive optocoupler series provides fast switching specifications allowing designers to use smaller filters, thus reducing overall system power consumption.

High Performance Optocouplers ON Semiconductor's 3.3V/5V high-speed logic gate optocouplers support isolated communications between systems without conducting ground loops or hazardous voltages.
Current Sense Amplifiers Current sensing requires accurate measurements and ON Semiconductor’s current sense amplifiers offer high degree of precision current sensing along with the advantages of wide input common mode range, bidirectional current sensing and high/low side current sensing.
Operational Amplifiers (Op Amps) ON Semiconductor’s wide portfolio of Op Amps features high performance devices which include low power, low noise, precision, power and also general purpose amplifiers.
High Current Gate Drivers The NCD5700 family of high current gate drivers is designed to keep high drive current through the Miller plateau to reduce switching losses.
