can someone post cisper 16
nmv found it
but wtf its some old ass indian standard. is it still relevant?
Also if you read research papers about inductors, they say a better solution is to put a RL in parallel with the L, rather then using just a R, since the R is kind of a RF shunt, and the extra L works as choke, but then you have mutual inductance between the two L's.
I already superglued a bunch of shit together and I forgot about the chassis so either I need to make the chassis really big or live with like a 45 uH LISN. I am also not modding or rewinding those big air inductors I made. Winding a giant air cored torroid like you say would just be way too much of a pain in the ass, I almost had a fit trying to wind that thick wire in 2 layers on my massive bobbins I made of PVC pipe and wood.
Its not easy. I had to wind a few layers of wire, use dowels/hammers to hammer the windings tight, glue, repeat... even winding it was difficult because its so thick, the best way I found was to screw the inductor to a table and walk around it in a circle pulling on it like I am trying to pull someone out of a cave. Then when you need to do the second layer you need to make a special dowel rod thing to beat the wire down neatly.
Can someone with a RF simulator do some explanations here? I think we need field solver data.
How do you even make a big ring bobbin? You need a wood lathe and some skills. . the only other thing I thought of is to fill one of those doughnuts you sit on after ass surgery or maybe some kind of tiny life preserver or something with concrete or maybe expansion foam, then coat it in hard resin/fiber glass. I guess you can just use a donut slice by gluing together a buncha ply wood you hit with a hole saw but that would make a curved rectangular inductor... given how hard it is to wind something big you might as well try to go for a ring. Maybe paper mache could work too if you can make a ring out of chicken wire. I do NOT want to file that kind of monstrocity. One unsafe ass way that comes to mind is to use a chain saw or use on of those super unsafe angle grinder disks that has a chain saw chain wrapped around it.
I would really like to see a simulation or more information before I fuck with that kind of pain in the ass shit though.
If you use a magnetic torroid then you can either have it work as a matched DM choke (where you wrap the wires together) or a kinda mixed choke that has some DM and some CM by winding it on opposite sides like a classical transformer.
