Speed up your design – and your engine – with inverter solutions from Infineon

Infineons solution Main inverter

A main inverter – also known as traction inverter  –controls the electric motor, converting DC to the AC needed to power the engine. The inverter can change the speed at which the motor rotates by adjusting the AC frequency.

We have an extensive, cost-effective offering of automotive-qualified silicon and silicon-carbide (SiC) discrete semiconductors and solutions supporting a wide range of motors, generators and power classes – all designed to increase inverter energy efficiency (through lower power losses) while shrinking size and weight. This scalable, highly reliable portfolio includes everything from IGBTs, MOSFETs and diodes through IGBT and MOSFET gate drivers to AURIX™ automotive microcontrollers.

Highlights of our offering include:

Power Devices

Our portfolio comprises cutting-edge IGBT power modules in different product families, configurations, current ratings as well as IGBT chip generations for an almost infinite number of applications. The well-known 62 mm, Easy and Econo families, IHM / IHV B-series, PrimePACK™ and XHP™ power modules are all equipped with the latest IGBT technologies. They come in chopper, dual, PIM, four-pack, six-pack, twelve-pack, 3-level, booster and single switch configurations with a current rating between 6 A and 3600 A. IGBT modules cover a range from only hundreds of watts to several megawatts.

Our HybridPACK™ Drive family allows designers to scale hybrid and electric inverters across different segments and performance classes in an easy and cost-efficient way. The portfolio consists of five different products (380 A/1200 V, 660 A/750 V, 770 A/750 V, 820 A/750 V, 950 A/750 V) – all with the same footprint. Our EDT2 IGBT technology offers best-in-class efficiency and robustness. Recently, we extended this product family with the following new devices: FS820R08A6P2BBPSA1, FS950R08A6P2BBPSA1, FS380R12A6T4BBPSA1, FS770R08A6P2BBPSA1 and FS660R08A6P2BBPSA1.

Striving for the highest standards in performance and quality, Infineon offers a comprehensive discrete IGBT portfolio that is second to none. New products are application-specific developed to achieve the highest value. They cover voltage classes from 600V up to 1200V, cover a wide range of current ratings as well as different packages.

Discrete-based inverters are known for being flexible, scalable, and cost-efficient systems. Due to their adaptable form factor, discrete devices provide a significant advantage for system integration. Parallelizing devices to reach different power classes enables a scalable inverter platform.

The new automotive IGBT discrete AIKQ200N75CP2  & AIKQ120N75CP2 are super efficient EDT2 IGBTs with co-packed diodes, designed for main inverter systems. The AIKQ200N75CP2 sets a new benchmark for component power density in a TO-247PLUS package.
