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

New GPS Data Helps Scientists Better Understand Ionosphere

The Global Positioning System (GPS) is a constellation of satellites orbiting the Earth approximately 11,000 miles in space. The GPS satellites in this animation are not drawn to scale. However, their orbits and orientation to the Earth are approximately correct. GPS satellites are organized into six different orbital paths completely covering the Earth. Looking at the Earth top down from the North Pole, the six orbits are spaced at 60-degree intervals. Looking at the Earth from the equator, each orbit is moderately tilted at 50 degrees.

A new data source to help scientists better understand the ionosphere and its potential impact on communications and positioning, navigation, and timing—an essential utility for many critical operations—is now available to the public. The data, which was collected by sensors on GPS satellites in 2018, was re

SwRI Receives $1.6 Million Contract for new Inspection Methods

The dark regions in this image show the “dirty white spots” sometimes found in nickel alloy engine components, anomalies that can lead to catastrophic failures. SwRI, under a new FAA contract, will develop new inspection methods to ensure anomalies like these are detected during the manufacturing process.

Southwest Research Institute is leading a team effort to develop new inspection methods for nickel alloy billet materials used in commercial aircraft engine components under a new $1.6 million Federal Aviation Administration (FAA) contract.
