Drsstc 4, I'm never stopping
« on: September 12, 2019, 02:36:00 AM »
With my 3rd drsstc coming to and end and the days getting longer it's time to build another indoor coil! Ever since I sold my first drsstc (a copy of mads drsstc ii) I always regretted it, i may rebuild it one day but for now I'm going to build something around the size of it.

Specs so far:

Secondary: 83mm diameter with a winding length of 220mm with about 1450t of 0.14mm wire (I'm assuming less turns because nothing is ever perfect). I'm estimating it will be about 180khz with a top load.

Bridge: I'm thinking about a dual full bridge of GP50B60 igbts. I've been working on a PCB that seems stable so this will be a test for it.

Driver: profdc9 tht ud2.7c. Dan if you're reading this I once again thank you. If it wasn't for you my builds couldn't happen, you've done outstanding work for the community.

Things I'm not sure of: I'm probably going to go way overkill with the mmc, bus capacitors will be ones I scrapped for solar inverters, unsure of primary form and am going to try smaller epocs n30 cores for the feedback and current CTS.

I'm hoping out of this I can improve my dual full-bridge board and be comfortable to release the design.

The only pic so far, I wish I got some better photos of when I was winding it. So far it has 3 coats of polyurethane, I'll apply another 3-4 coats and start sanding to get a smooth finish with a final coat to hopefully get a glass like finish.
