Hi All,
I am trying to get my head around planar transformers and how they are physically connected in the real world. I was originally under the assumption that one would create a single 4- or 6-layer board (for example) with each layer containing a planar coil which represents a transformer wire/inductor. However, I have been looking through Standex Mayer transformers, see page 10: https://standexelectronics.com/wp-content/uploads/SME-Planar-Magnetics-Design-Guide_web_en.pdf
And it looks like there are individual PCB boards, which are connected together individually through mechanical connectors. What is the benefit of having individual PCB's connected up in this fashion, rather than just having one single multi-layer board which performs the same functions?
Are these going to be multiple single layer boards (4 to 6 of them) all connected to each other via the mechanical fastenings, or alternatively, is each individual board its own multi-layer board, so that in effect we have a collection of multi-layer boards which each represents a transformer winding?
Hopefully by including the Standex transformer reference here some can understand my confusion and help me understand this physical configuration a little better?
TIA!
