Eddy-Current Effects In Magnetic Design (Part 2): The Proximity Effect

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
