Shrinking the core
2014-04-08 21:17:00| Transmission & Distribution World
Power electronic transformers break new ground in transformation and transportation The size of a transformer core is dictated by the frequency, and the frequency is given. Therefore, or so traditional wisdom suggests, transformers cores cannot be shrunk beyond a certain point. This paradigm, that has dictated the minimum size of power transformers for more than 120 years is about to be broken. The innovation behind the power electronic transformer says that even though the network frequency is given, power electronics allow the local frequency to be changed. At the same time, this frequency conversion means that the input frequency need not equal the output frequency, or can even be DC. read more

Mother Nature Network: Some of the best habitats in North America for salamanders are showing strain from climate change, becoming warmer and drier as global temperatures and weather patterns shift. This means the salamanders living there, which rely on cool, moist forests, are also experiencing changes. Forced to burn more energy to deal with the changing clime, the salamanders are getting smaller in average size. Research from the University of Maryland, published yesterday in the journal Global Change Biology, shows...
