Wolfspeed has introduced two new 3.3 kV silicon carbide power module families aimed at addressing rising power conversion demands driven by AI data centers, renewable energy systems, and broader electrification trends.
The launch includes a high-power half-bridge baseplate module for applications exceeding 800 A, as well as a scalable full-bridge baseplate-less module under the WolfPACK® platform. Both are designed around industry-standard footprints and target next-generation medium-voltage power architectures.
The baseplate module is optimized for high-power applications such as solar inverters, wind energy systems, and grid-scale storage, while the WolfPACK® family is focused on modular solid-state transformer (SST) architectures and renewable energy infrastructure. The flexibility of the baseplate-less approach enables series-stacked and multi-level converter configurations, supporting scalable high-voltage systems.
Technically, both module families are designed for continuous 24/7 operation in 2 kV+ DC-link environments. They incorporate advanced packaging technologies such as sintered die attach, improved encapsulation materials, and enhanced cosmic ray robustness to improve reliability and power cycling performance.
From a performance perspective, the new baseplate module reportedly delivers up to 42% lower switching losses compared to competing SiC solutions and more than 90% lower losses compared to traditional IGBT systems under comparable operating conditions. The WolfPACK® architecture also enables significant reductions in system footprint, supporting more compact solid-state transformer designs.
