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

HiperPFS-4 with Integrated 600 V Qspeed Diode Application

Two of the main issues for modern power supply designers are the elimination of unwanted line harmonic currents and ensuring a power factor that is as close to unity as possible. Unwanted harmonics can cause transmission equipment to overheat and pose interference challenges that must be addressed later; both a

BridgeSwitch Application

Electric motors are currently the largest consumers of electricity in the world by a large margin. The Energy Research Centre of the Netherlands (ECN) estimates that 45% of all electricity generated globally is consumed by electric motors. Therefore, as part of the push towards higher efficiency, legislation is

Harvard Researchers use Dyes to Store Data

Amit Nagarkar helped develop a data-storage system that uses fluorescent dyes.

In the digital age, every byte of data needs to go somewhere — and preferably stay there a long time. That last part is a major problem when it comes to data-storage systems, which typically last less than 20 years. A group of Harvard chemists is trying to solve the issue with an innovation that resembles ti
