Researchers have developed a new power module to optimize data center efficiency. It promises up to five times higher energy density with low resistance.
Global energy demand is continually increasing. One reason is the increasing spread of AI systems. Researchers at NREL recently presented an approach to reduce the energy requirements of data centers: a new power module based on silicon carbide.
The scientists achieved efficiency and storage density values ​​that had never been seen before. The system is called Smart Power Module with Extremely Low Inductance (ULIS). It is said to have an energy density that is up to five times higher than previous silicon carbide-based approaches.
As a result, manufacturers could produce more compact, lighter and more energy-efficient systems. These include data centers, power grids, microreactors and aircraft.
New power module could tackle energy crisis
In total, the ULIS can provide up to 1,200 volts and 400 amps. Another advantage is an exceptionally low parasitic inductance. This is the internal resistance that limits the speed at which current can be changed.
By reducing it by a factor of seven to nine, more energy can be extracted from the same power source. In addition, ULIS is said to be particularly suitable for rapidly changing environments. The power module should continuously check its own status to prevent errors.
Researchers are rethinking design
The main factor of the new power module is a completely new design. In current modules, the components are housed in a brick-like housing. In contrast, ULIS’s circuits are wrapped around a flat, octagonal design. This shields external interference factors and can accommodate additional components in the same space.
Another advantage lies in the material of the housing. It is based on a plastic and therefore has a lower weight. The system can also be operated completely wirelessly. This makes it more flexible to use.
