Infineon introduces 2300V SiC modules for energy systems

Infineon has recently expanded its XHP 2 power module range by introducing 2300 V CoolSiC MOSFET variants tailored for high-voltage energy systems. These SiC modules are capable of supporting DC-link voltages up to 1500 V, aligning with the industry trend towards higher system voltages in renewable energy infrastructure. This development is particularly significant for eeNews Europe readers as it directly addresses key factors such as efficiency, power density, and thermal performance in large-scale converters commonly utilized in wind, photovoltaic, and battery storage systems.

The XHP 2 CoolSiC MOSFET modules have been meticulously engineered to minimize switching and conduction losses when compared to traditional silicon-based alternatives. This enhancement offers inverter designers the opportunity to enhance efficiency and power density, or alternatively, increase switching frequency to mitigate harmonics and reduce overall system size. Infineon is offering these modules with on-resistance values ranging from 1 mΩ to 2 mΩ, along with isolation voltages of either 4 kV or 6 kV. Additionally, the XHP 2 package supports symmetrical switching behavior, simplifying paralleling in large power converters.

Enhanced SiC Module Platform

These modules feature Infineon’s .XT interconnection technology, aimed at bolstering reliability and operational longevity. Certain variants also come equipped with pre-applied thermal interface material, streamlining assembly processes and promoting consistent thermal behavior. Infineon has reported promising system-level outcomes in various renewable energy applications. In a wind power demonstration system, the modules achieved an impressive power density of 300 kW/L. Similarly, tests conducted in battery storage systems demonstrated semiconductor losses of less than 0.7 percent of the total output power.

Focus on Renewable Energy Applications

Infineon has made the 2300 V XHP 2 CoolSiC MOSFET modules readily available through its own channels and distribution partners. The specific variants currently listed include FF1000UXTR23T2M1, FF1300UXTR23T2M1, FF2000UXTR23T2M1, and FF1000UXTR23T2M1_B5. These modules represent a significant advancement in power module technology, catering to the evolving needs of high-voltage energy systems and offering tangible benefits in terms of efficiency, power density, and thermal performance. As the renewable energy sector continues to expand, innovations such as these will play a crucial role in driving progress and sustainability within the industry.
