Electric vehicle power conversion (EVs & HEVs)

Reach efficient EV power conversion with our scalable OBC solutions

Infineon provides comprehensive and complementary chipsets for designing modular and scalable on-board battery chargers (OBC). By harnessing our expertise in power electronics and semiconductors, we deliver OBC solutions that utilize Si, SiC, and GaN power technologies, ensuring high quality and safety standards in automotive applications. Increasing power levels, bi-directional operation support (V2X), and faster adoption of 800 V battery systems have introduced new levels of complexity to OBC designs. This complexity is heightened due to higher power density, efficiency, and overall cost requirements. Leveraging WBG semiconductors, SiC and GaN semiconductors have revolutionized electric vehicle power conversion by enabling unprecedented levels of efficiency and performance while coexisting with cost-effective silicon (Si) technologies. Power switches, paired with optimized gate drivers, complemented with modern microcontrollers (MCUs) and other system components such as OPTIREG™ PMICs, XENSIV™ current sensors, CoolSET™ auxiliary controllers, and others, are enabling customer designs for future electric mobility.

Infineon is the leading semiconductor supplier for automotive high-voltage to low-voltage DC-DC applications. Our wide range of products for HV-LV DC-DC converters, including sensors, controllers, and actuators, provide high-efficiency and high-power density options for HV to 12 V, HV to 24 V, and HV to 48 V applications. Our products are designed for functional safety and reliable operation, leveraging Infineon's technology and expertise. With Infineon's complete and competitive chipset solutions, automotive manufacturers can develop automotive HV-LV DC-DC applications that offer superior performance and meet the demands of today's and future electric vehicles.

Smart and safe in-vehicle charging connectivity modules

Charging an electric vehicle (EV) requires communication between the vehicle, the charging unit, and the power grid. Possibly even connecting the vehicle to the smart home for even more comfort. Especially with bi-directional charging upcoming, this communication will require an even deeper interaction within the vehicle as well as with the consumer and energy provider. The current state of the battery, the user's requirements, or smart home requirements need to be aligned with the available energy source and the energy provider, possibly including automated billing features. Communication standards for this purpose are defined in the ISO 15118. With Infineon's expertise and broad product portfolio, we enable our customers to develop solutions that meet the ISO 15118-defined requirements and beyond. The TPM module, in combination with the AURIX™ microcontroller family, allows for secure communication. The Wi-Fi/BT module complements the power line communication, and with attached memory, data can be locally stored and updated. Finally, our wired connectivity solutions, such as CAN transceiver, complement the communication needs for the system.
