My second DRSSTC
« on: March 16, 2023, 03:40:21 PM »
I was seccesful making my first DRSSTC and now I am starting work on my second one.
This is the render of a not detail 3d model i made for this coil.

I have almost completed the topload all it is missing is some heat inserts in the 3d printed parts.


I also started making the secundary coil. I made a rig to help me wind the coil but I ran into a issue i didnt experiance before. I wound the coil completely with heating turned on.

I left the coil overnight and when i came back tomorrow the windings were lose. I am guessing thermal expansion/contraction of the PVC is to blame. I dont have the image of the lose windings as I am already rewinding the secundary. I was wondering is this a common issue and are there ways to prevent it?

I will post more detail about my coil during weekend. I was just too curious about the thermal expansion problem that i had to ask right now.

I had a bit of that issue winding my DRSSTC secondary.  24AWG on 160mm diameter made it a bit less problematic.  I just coated with urethane epoxy in spite of windings being loser than desired.
I've been more concerned about heating during high-power operation, especially when running on a warm summer evening, well warmer than when I wound and coated the secondary.  Fortunately I haven't noticed any delamination after cool-down.

It's been some time since I last posted. A little more than anticipated but I am writing an update.
The lose winding on the secondary were fixed by using a different pvc pipe. And I have coated the secondary in a thick layer of epoxy to try and prevent any future damage. Here is an image of the coil and primary.


I will probably have to use another source of aluminum pipe because the current one is quite expensive and is anodized so the surface isn't very well conductive.


The breakout is made from a aluminum rod sharpened on the top and threaded on the bottom. It attaches to the rings of the topload using a wire that is wound between the rings. U git the idea from https://highvoltageforum.net/index.php?topic=759.0


Did anyone begore use aluminum/copper lightning rod grounding wire to make a topload. Per meter the aluminum grounding is cheaper than the pipe that I can get in the hardware store. If I failed to explain what I am talking about here is an image of a sample of the copper variant.



Ok I promised more details about the coil. Attached is a JavaTC file for the plans I have. As I wanted to practice PCB design I recreated the UC2.7c and easy bridge by Loneoceans. Here are the files of my attempt at PCB design. https://github.com/miki407/DRSSTC
And for those that dont want to download the files just to view them here are some previews made by InteractiveHtmlBom:
Control Board - https://htmlpreview.github.io/?https://github.com/miki407/DRSSTC/blob/main/Controller/DRSSTC%20controller/bom/ibom.html  //I added my nickname to the PCB but it is not with intention to discredit the original designer.
Full Bridge - https://htmlpreview.github.io/?https://github.com/miki407/DRSSTC/blob/main/Full%20Bridge/Full%20Bridge/bom/ibom.html

These are the circuit boards I ordered and will be using un this project. The components haven't yet arrived but soon I will start assembly and write more when I make some progress.

My current task is to make a primary. Original plan was to 3d print the holders but they might melt so I will have to find a different solution.

If you have any questions please ask. I would be glad to answer them the best I can.
