Electrification is the process of replacing technologies that directly burn gasoline, diesel, natural gas, or other fossil fuels with equipment powered by electricity. Common examples include replacing combustion vehicles with electric vehicles, gas furnaces with heat pumps, and fuel-powered industrial machinery with electric systems. When paired with renewable energy, nuclear power, energy storage, and a…

UL Solutions launched a manufacturer-focused certification program for medium-voltage solid-state power units that can support direct medium-voltage-to-800 VDC power delivery in AI data centers.
-
Article 2 introduces voltage, current, resistance, Ohm’s law, and electrical power as the foundation for later field and data-center electrical training.

Mitsubishi Electric’s new NVIDIA-compatible AI data center reference design integrates 800 VDC power, on-site generation, battery storage, microgrids and dual-loop cooling for Vera Rubin infrastructure.
-
The European Commission has proposed a common sustainability rating system for large data centers as Europe prepares for rapid growth in artificial intelligence infrastructure. Facilities with installed information technology capacity of at least 500 kW already report operational data under EU energy efficiency rules, and the proposed rating system will turn reported information into comparable…

Starcloud plans to put Bitcoin-mining ASICs aboard an orbital data-center spacecraft, testing whether solar power can outweigh the challenges of cooling, launch cost and hardware reliability.
-
800 VDC data-center power is moving from reference architecture toward working conversion hardware, protection frameworks and deployable high-density compute systems.

A semiconductor and a transistor are closely related, but they are not the same thing. A semiconductor is a class of material—most commonly silicon—whose electrical conductivity can be precisely controlled. By modifying semiconductor material through processes such as doping, engineers can create regions that either provide or restrict the movement of electrical charge. These properties…

An electrical schematic is a symbolic representation of how components within an electrical or electronic system are connected. Rather than attempting to reproduce the physical appearance of a circuit board or machine, schematics use standardized symbols to describe components and electrical relationships. A technician can therefore examine a schematic and understand the intended current paths,…

A bushing transformer is a power transformer component that uses electrical bushings to safely carry high-voltage electrical current through the grounded steel tank of the transformer without allowing electricity to short to the enclosure. Bushings provide electrical insulation while creating a secure connection between the transformer’s internal windings and the external power system. They are…
