#90🚀 Coreless Magnetics with LK-99

SuperPowers for Electrical Engineers 🦸🏻‍♂️🦸🏼‍♀️

In my previous NL, I was saying…

If we would use LK-99 in the magnetics…

My first draft:

1. DC losses are not important anymore. Therefore, I can have infinite turns to decrease the core losses.

2. However, the AC losses won´t disappear because they are related to electric fields opposing the circulation of the current through the conductor and more turns, layers, and higher losses.

3. We must find an optimal design to balance AC and core losses.

4. For High-Frequency inductors, I would use a single-layer winding with smaller wires and add enough distance between wires to reduce AC losses.

I was wrong…in an ideal case, AC losses will also disappear…

Second Draft:

1. DC and AC losses are not relevant anymore

2. I can use all the wire I want. Therefore, I can have infinite turns

3. I can build a close structure of wire to keep the magnetic field inside the loop and reduce EMI noise

4. I don´t need a core because I can get the required inductance by increasing the turns without penalization of losses

What do you think?
