These days, homeowners are clamoring for pendants that hang from the ceiling, moody undercabinet lighting, recessed lighting and outdoor path lights that illuminate the edge of the front walk. Of ...

Maybe I'm describing a unicorn device here but I have a bunch of devices that run off DC-in of various voltages, and take a barrel jack connector for power. They all have their own wall warts but I've ...

There are several ways to convert an AC voltage at a wall receptacle into the DC voltage required by a microcontroller. Traditionally, this has been done with a transformer and rectifier. However, in ...

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 ...

A well-known solution for electrical noise in industrial plants is the constant-voltage transformer, or CVT. These devices can filter distortion and notches from input voltages (see Fig. 1). CVTs have ...

Single-transistor forward converters are popular in higher-power isolated power supplies because they feature low parts count and component stress. On the downside, careful attention must be given to ...

A three dimensional seismic isolation system was developed and experimentally validated for high-voltage electric power transformers of weight in the range of 300 to 800kip. Although the validation ...
