The National Renewable Energy Laboratory (NREL) has launched ULIS, an Ultra-Low Inductance Smart power module utilizing silicon carbide semiconductors. This 1,200-volt, 400-amp module features a compact, disk-shaped design and offers high power density with minimal energy loss, making it applicable for data centers, grids, microreactors, and heavy-duty platforms.
The module's innovative flattened octagonal architecture reduces parasitic inductance by 7-9 times compared to existing silicon carbide modules. Additionally, it employs a bonded copper design with flexible Temprion polymer, which decreases weight and allows for lower-cost manufacturing using standard tools. A pending patent for its low-latency wireless control protocol enables operation and monitoring without physical cables.
