I well remember when, in EE Times, the merits of the (then brand new)
switch mode power conversion units was covered in a number of issues.
Efficiency over the linear supplies was the golden egg. They were touted
as the best thing since sliced bread for efficient power conversion.
Fast forward a year or so. Same publication. Now EE Times was covering
the RFI caused by their newest baby, switch mode power conversion units.
It was major. Then another 6 or so months, all kinds of articles on how to
tame the RFI from SWPSs.
Something similar needs to occur with the present mess associated with wall
warts and, in general, even more switch mode power conversion units.
