Figure 1: PRM™ and VTM™ are the building blocks of FPA. PRMs are selected based on the system input voltage range and power requirements; VTMs are selected based on the output voltage range and current requirements. The PRM can be mounted anywhere in the system where convenient; the VTM should be mounted as close to the processor core as possible

The recent introduction of new clustered AI ASIC processor based supercomputers are pushing the boundaries of power delivery networks to levels that were never imagined just a few years ago. With current levels approaching 100 kiloamps/ASIC cluster, innovation is needed across power system architectures, topologies, con

Valve Testing Capabilities to aid Carbon Capture, Storage

The Flow Component Testing Facilities (FCTF) consist of a number of dedicated facilities housed in a single location that are used to perform both standard and custom testing. SwRI engineers will be exhibiting the Institute’s CO2 SSSV testing capabilities, as well as the other FCTF valve testing capabilities, at the Valve World Americas Expo & Conference in Houston, Texas Oct. 13-14 at Booth no. 405.

The Southwest Research Institute (SwRI) Nitrogen Blowdown Facility has succeeded at recreating the intense conditions of a gas event, making it possible to test subsurface safety valves’ (SSSV) ability to withstand associated gas flow rates at high pressures to prevent injury, loss of life and environmental ef

Single-Atom Catalyst Produces Hydrogen from Urea

▲ The schematic diagram for the UOR process using high-loading RhSA stabilized on strained oxide surface (left). Full urea electrolysis system for green hydrogen evolution (middle). Energy-saving urea electrolysis compared to water electrolysis (right).

While hydrogen is widely suggested as an alternative fuel with zero carbon emission, the majority of commercial hydrogen fuel production is obtained from the refining of fossils fuels. The limited reservoir of fossils fuels and their negative impact on the environment has encouraged researchers to develop alternative te
