It won’t have an immediate transformative effect on troublesome shortages, but a new U.S. Department of Energy (DOE) ruling brings more clarity to solving the long-term puzzle of future transformer ...

Have you ever noticed those metal canisters attached to utility poles? Those are transformers. They convert high-voltage electricity from power plants to lower-level electricity that’s safe for homes ...

Several switching-converter topologies exist for power converters that operate from the ac mains and must maintain a power factor of 0.9 or better. One topology is a boost converter with a control ...

Vision transformers (ViTs) are powerful artificial intelligence (AI) technologies that can identify or categorize objects in images -- however, there are significant challenges related to both ...

In the era where electrical systems are a vital part of day-to-day life, the safety as well as efficiency of electrical ...

For the PDF version of this article, click here. Among the first decisions engineers must make when designing a new switchmode power supply are transformer size, working frequency and the selection of ...

That’s when new DOE minimum efficiency requirements kick in for both medium- voltage dry-type and liquidfilled transformers and induction motors. That’s a lot of transformers and motors. Approximately ...

Three major electric power trade groups in a letter on Feb. 15 urged the Department of Energy (DOE) to reconsider proposed energy efficiency conservation standards for distribution transformers, ...

Growing data center power demands are driving server end-equipment manufacturers to reach higher power-conversion efficiencies in order to reduce the thermal footprint of their systems. The transition ...
