Last week I talked about the inbred world of the academy. This week, honoring that, I bring a brief overview of an article by two Top professors in Magnetics, Charles Sullivan and Minjie Chen.
The article is about the models of coupled inductors and their models for it. I have made a first read (Definitively I need a second and a third one to get all the knowledge they are representing)
In order not to go into too much detail, I am going to comment on one thing that seems useful to me to understand any magnetic model.
By the way, let's see if Premo (the magnetic manufacturer) understands that its 3D power is nothing more than 3 coupled inductors with different coupling factors. I tried to buy one unit to do some measurements but they reject me. The same thing happened with Ray Ridley.
Coming back to the article. The concept of series and parallel coupled structures.
This concept is very important for building any complex structure and the complexity of the analysis can be seen in this article. Folks, this is not as simple as doing some drawings on an Ipad on a train and doing a patent, you need to study the theoretical impact.
👏 Thanks Chen and Sullivan for helping the community in this topic
This concept basically affects the calculations of the coupling coefficients between windings, which affects radically the final inductance seen by the circuit.
📣 Where are you storing your designs?
One of the problems I have seen in the industry is the digitalization process.
It’s funny because I’m learning a lot about our own users. A lot of them are using Frenetic as their repository of Magnetics and orders.
I invite you to a demo. Write to me an email!
“Best magnetics design platform available today and constantly getting better” – Bob White - President And Chief Engineer -Embedded Power Labs.
“I value especially the freedom to model many different inductors before selecting a single one. The "Suggest Wire" feature - it truly is great!”-
Don Lucas – Senior Power Electronics Engineer at Lucas Consulting Services.
