SiC modules simplify high-voltage topologies
Two 3.3-kV SiC power modules from Wolfspeed target high-voltage energy infrastructure, including AI data centers, renewable energy systems, and grid equipment. The HAB900C33LM4 half-bridge baseplate module supports applications above 800 A, while the IBB020A33GM4 full-bridge baseplate-less module is rated for 100 A. Both modules accommodate 2-kV and higher DC-link architectures, allowing designers to reduce power stages and use simpler 2-level topologies.
Part of the LM platform, the HAB900C33LM4 half-bridge module is intended for converters used in solar, grid-scale energy storage, and wind-power systems. Wolfspeed states that it delivers up to 42% lower switching losses than comparable SiC products and more than 90% lower switching losses than IGBTs under the same test conditions. A member of the WolfPACK family, the IBB020A33GM4 baseplate-less device is designed for modular converter architectures, including solid-state transformers and series-stacked or parallel systems.
Both power modules use Gen 4 SiC technology and advanced packaging techniques, including sintered die attach, to enhance durability and power-cycling performance. Wolfspeed says the modules also maintain switching performance over temperature, helping reduce the size of magnetics and EMI filters while increasing system power density.
Samples of the HAB900C33LM4 and IBB020A33GM4 in industry-standard packages are available through Wolfspeed’s direct sales representatives.
