A power transformer technology developed by Plitron Manufacturing Inc. of Toronto, Ontario, attenuates differential and common-mode noises on the ac mains to the extent that external filtering may be ...

RAMSIS GIRGIS, MATS BERNESJÖ - Everyone is familiar with the characteristic hum that transformers produce. In sparsely populated areas, this drone will disturb few, but in urban areas it can be of ...

I just got the latest Hifi News magazine and, as usual, the same ridiculously expensive mains cables etc are being pimped. I usually just skim over that crap, after admiring how pretty it is, but this ...

Common-mode noise reduction has emerged as a critical focus in the development of power converters, addressing challenges associated with electromagnetic interference (EMI) that can impair both ...

The mains of the world were constructed as a giant copper causeway to transport electricity from the generating station to our homes and factories. Today's problems on the mains were unknown a few ...
