SUMMARY

The discussion centers on inductive power transfer devices, specifically focusing on the concept of inductive coupling. Participants clarify that while similar to transformers, these devices allow for separation between induction coils, making them suitable for applications where traditional plugs are impractical due to environmental factors like dust. Terms such as "magnetic amplifier," "isolation amplifiers," and "inductive coupler" are suggested as relevant keywords for further research.

PREREQUISITES
  • Understanding of inductive coupling principles
  • Familiarity with transformer functionality
  • Knowledge of magnetic amplifiers
  • Basic concepts of electrical isolation techniques
NEXT STEPS
  • Research "inductive coupling applications" for practical implementations
  • Explore "magnetic amplifier" technologies and their uses
  • Investigate "isolation amplifiers" and their design considerations
  • Learn about "inductive coupler" designs and specifications
USEFUL FOR

Electrical engineers, product designers, and anyone involved in developing wireless power transfer solutions will benefit from this discussion.

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!
