Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

So you have an old tube-type transmitter as a backup. It ran perfectly when you last turned it on two years ago to substitute for your then-ailing solid-state main transmitter. Now you need it again.

Most electrical engineers believe they have a good understanding of power supplies because they are relatively simple, single-function DC devices designed to output controlled voltages. However, there ...

[Ladyada] is working on a tutorial series covering power supplies. If you’ve ever built an electronic project you’ve used some type of power supply but we think that most people have no idea how you ...

As part of a power electronics design project involving a 3.6-V dc-dc converter, it became necessary to test and accurately characterize the planar transformer shown in Fig. 1. Transformer operating ...

Read an introduction to this series in Part 1, and Part 2, which covers noise. This is the third and final part in a series which discusses how to properly test a power supply to ensure it will work ...

Omicron will present an informative technical tutorial, “A New Approach for Testing Instrument Transformers,” on its Roadshow Bus in Booth 2739 during the 2014 IEEE PES T&D Conference & Exposition in ...
