Re: Transformer history
Of course, these transformers are rather more sophisticated that the ones that George Westinghouse and Charles Steinmetz were working with. Somewhat wider bandwidth and more predictable response with regard to common- and differential-mode behavior.

Re: Transformer history
Sorry,I forgot to include the link to an interesting resource on their history:

http://edisontechcenter.org/Transformers.html

and there are many more you can find.

Transformer history
Interesting that the transformer--among the oldest electrical components--still finds so may roles. The induction principle was discovered in the 1830s, and the first commnercial transformers were used in the 1880s--but they were for power, not signal.

A properly designed and used transformer can be an extremely reliable device and a solution to a lot of problems in signal isolation, baluns (as this blog shows), power transfer, voltage/current step-up/down, impedance matching, and many others. Not bad for a "dumb", passive part!

I need 100-dB dynamic range for a medical imaging application. Can you help me choose between successive-approximation and sigma-delta ADC architectures?
Without even thinking about it, consumers depend on technology throughout the day as they send texts, turn on lights, and drive home from the office. But that technology depends on something that usually goes unnoticed until there's a problem.
I thought it would be good to continue looking at the example I gave in my last blog where we looked using fewer LDOs and combining power supply rails on an ADC while maintaining isolation with ferrite beads.
Electronic equipment and power management is becoming increasingly critical as our power grid ages and renewable energy comes on line. In response, new technologies are being developed to protect equipment from power disturbances and fluctuations.
