2 diodes change demagnetization-signal polarity - 04/12/01 EDN-Design
Ideas....Power-supply designers usually like flyback converters to operate
in DCM (discontinuous-conduction mode) rather than in CCM
(continuous-conduction mode). In DCM, the flyback converter is a first-order
system at low frequencies, which eases the feedback-loop compensation. You
can use a low-cost secondary rectifier... [Design Idea by Christophe Basso,

Electromagnetic field detector (mitedu) - This circuit is sensitive to low
frequency electromagnetic radiation and will detect for example hidden wiring or the
field that encompasses a transformer. Pickup is by a radial type inductor, used as a
probe which responds well to low frequency changing magnetic and electric fields.
Ordinary headphones are used to for detection. The field that surrounds a transformer
is heard as a50 or 60Hz buzz. (added 5/02) |

Electromagnetic field detector (tomi.geo) - This lovely circuit is a real
gem! Easy to assemble and more sensitive than many commercial devices available. It's
based around an LF351 low-noise operational amplifier and a 1mF choke acting as the
sensor. Unlike most other simple EMF detectors, this one has a meter output for
accurate reading, but alternatively, you can also roughly....(added 10/05)
