What is the name for wireless AC power transfer between inductors?

[enigma]

Hi all,

I'm looking for general information on an inductor type device which transfers AC power to a separate, unconnected (but nearby) inductor. If I were to try googling it, what should my searchword be?

Do you mean a transformer? Or possibly a resonator?

Kinda like a transformer, but the two induction coils need to be able to be separated.

The application is this: powered chassis, unpowered module which draws power from and can (and will) be removed from the chassis. The environment is such that plugs would not be an optimal design choice due to excessive dust.

"Unconnected" connotes "no common core" --- you can try "magnetic amplifier" --- it's a mixed bag in terms of actual magnetic amplifiers and assorted AC/DC, DC/DC, AC/AC, and DC/AC converters. You are perhaps looking for "isolation amplifiers." Trying for electrical isolation?

My electric toothbrush works like that.

I have never heard the device given a name. I have used this principle, and we have always called it inductive coupling. Maybe inductive coupler is a good name.

Thanks all!
