Nye SiC-baserede invertere bryder temperaturgrænser

Infineon præsenterer nye SiC-baserede automotive invertere, der kan kan operere ved langt højere temperaturer end eksisterende løsninger (in english).

Infineon Technologies has achieved a new milestone in power modules for electric vehicle inverters. The company is introducing a new 1300 V silicon carbide (SiC) module within the HybridPACK Drive family that is capable of continuous operation at temperatures up to 205 degree C. Existing designs typically allow up to 175 degree C.

This increase enables automotive OEMs and Tier 1 suppliers to deliver higher peak and continuous output power from existing inverter designs or, in new designs, reduce system complexity and overall cost. 

- We are committed to advancing the performance and efficiency of electric vehicle drivetrains through cutting-edge innovation in high-voltage power products, says Stefan Obersriebnig, Senior Vice President and General Manager Automotive High Voltage at Infineon, and he continues:

- Higher operating temperatures provide our customers with more design flexibility and enable them to lower system cost. This innovation will help them to build even more competitive platforms that accelerate the adoption of electric vehicles.

The increased operating temperature enables up to 15 percent higher output current compared to existing designs, directly translating into higher inverter power density. At the same time, maintaining identical module size, footprint, and interfaces allows seamless integration into existing platforms and enables performance upgrades without costly redesigns or extended development cycles. This drop-in compatibility accelerates time-to-market for next-generation inverter designs while leveraging proven manufacturing and qualification processes.

The extended temperature capability can also significantly reduce cooling system requirements. By tolerating higher junction temperatures, inverter designs can be optimized with smaller or less complex cooling systems, helping to lower system cost, reduce vehicle weight, and improve overall energy efficiency.

In addition to the higher operating temperature, the new module is the first one in the HybridPACK Drive family to come with a 1300 V blocking voltage to improve inverter performance, efficiency and robustness beyond battery voltages of 900 V.
