Eddy-Current Effects In Magnetic Design (Part 2): The Proximity Effect
by Dennis Feucht, Innovatia Laboratories, Cayo, Belize, How2Power Today, Sep 15 2016
Focus:
Having introduced the skin effect in part 1, this article now turns its attention to the other
eddy-current effect—the proximity effect which occurs between conductors and dominates over the
skin effect for multiple winding layers. Before describing the proximity effect, this part will
establish the general equations for frequency-dependent resistance as these will be useful
later in determining power loss caused by skin effect and proximity effect.
What you’ll learn:
- How to understand the origins and impact of the proximity effect in transformers and coupled inductors
