The more power you move through a system, the more carefully it must be controlled. Nowhere is this principle more visible today than in the rapid expansion of data center infrastructure. Just a few years ago, a typical server rack in a data center might have required around 10 kilowatts (kW) of power. Today, that number has already grown significantly to 120 kW.

As AI data centers move from 54 V in-rack distribution to 800 V DC, power shelves and racks must be validated at full voltage against load steps that can swing hundreds of amps in microseconds. Tektronix is addressing that with the EA-ELR 21000, an auto-ranging, high-dynamic electronic load test system built on a fully regenerative architecture for ±400 V and 800 V DC power. The EA-ELR 21000-80 4U HS is a 30 kW regenerative load module rated for up to 1,000 V and 80 A.

CF390MK-10.5 towable sandblasting compressor for sale is a trailer type design. This robust portable air compressor for sandblasting is engineered to deliver a consistent airflow of 11.0 m³/min, providing reliable performance in diverse industrial applications. Its trailer configuration ensures mobility, allowing you to transport this powerhouse effortlessly to various job sites.

STMicroelectronics has released the L9962, a lithium battery-management IC designed for portable equipment, light electric vehicles, and backup energy storage systems. The L9962. The chip handles cell monitoring, passive balancing, overcurrent protection, and thermal management for packs containing four to ten series-connected Li-ion or Li-polymer cells, while integrating enough ancillary functions to meaningfully reduce external component count in battery-pack designs.

As cloud computing and AI workloads accelerate the transition to 800G and 1.6T optical interconnects, rising heat density inside compact transceiver packages has become a critical design constraint. To explore how thermal interface materials are evolving to balance high conductivity, processability, and optical-grade cleanliness, EEPower spoke with Dr. Zou Lu, a Technical Service and Development Scientist at Dow.

Bel Fuse has announced its XRCM 200 and 300 Series, a new family of second-generation DC-DC converters engineered to meet the demanding reliability and power requirements of modern railway and transportation systems. Designed for high efficiency and high power density, the new converters allow engineers to simplify power architectures while strictly adhering to the latest safety and performance standards required in the transit industry.

Enhancement-mode GaN HEMTs feature fast switching speed, low on-resistance, and high power densities. As such, they are ideally suited for use in high-frequency, high-efficiency power conversion and RF circuits.

Startup Bluecore Energy has assembled a non-fueled prototype of a 10 MWe water-cooled nuclear reactor, with the ultimate goal of deploying a power-generating barge in Long Beach Harbor. After testing and approvals, this floating nuclear generator could deliver grid-connected, on-demand electricity to support port activities, coastal AI data centers, and surrounding communities.

From the smallest component to the largest power plant, power electronics must continually innovate to make the most of resources, production, and operations. In recent developments, Google has partnered with Georgia Power to expand nuclear capacity, while China Huaneng Group is establishing a supercritical carbon dioxide and molten salt storage plant.

This article is published by EEPower as part of an exclusive digital content partnership with Bodo’s Power Systems. As industrial DC power systems continue to increase in power density, redundancy has evolved beyond a simple means of improving system availability. Modern control cabinets, telecommunications infrastructure, and industrial automation systems are expected to maximize uptime while simultaneously reducing energy consumption, cabinet temperatures, and maintenance effort.
