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