What driver to use for first DRSSTC build

[thedoc298]

I am 65 and retired repair man. I have built a couple of srsgtc one 6 and one 4 both with about 2kw input (small) and it's been a real rush but I want to start a drsstc for my next prodj.
I have been reading these forums for years and years and years it seams.
Anyway I ordered some 2.7c pcb and had them for months. I finally got around to ordering the bits and of course they don't have everything in the list.

So I found a couple of boards on ebay that seam to be what I need and the one looks like it is close to the 2.7c in features anyway. I just don't know enough about the solid state side of the coil to buy these. I would like to start with these two boards as my first drsstc and when the bits come in for the other boards I will be making them.
Their seams to be plenty of techno info for drsstcc on hear to get me up and running.
Could someone look at these two and tell me if they might work ok. I will be making the end part, the part with the cm300's my self, I do have a full shop.

Thanks, I'm drooling to get going. Thanks

Hi

we had few threads on the forum regarding chinese DRSSTC drivers and their disadvantage is complete lack of documentation
I'm sure most of them work fine, but I suggest that you go for UD2.7C since it'll be easier to solve any problems you might encounter

Good luck and happy coiling!

While I was reading this, the postman delivered the rest of my parts for my ud2.7c, yea

I still ordered the other 2 boards, will be fun to check out.

For smaller DRSSTCs I often recommend using the Universal Driver 1.3b, because its so simple that it is easier to understand what is going on. Step it up a bit with Universal Driver 2.1b or the UD2.7/UD2.9 PCB packs with even more features. The reason is that pulse skipping, free-wheeling and QCW are all advanced driving methods that could cause more confusion in the start compared to a regular feedback-only or phase-lead driver. My DRSSTC1 still runs on a UD1.3b

For the Chinese drivers, the best we can offer is the different threads collected here: https://highvoltageforum.net/index.php?topic=573.0

Hello Mads, I thought that one needed the phase compensation or bad things happen, but I guess not with others using drivers without that feature.  How bad is it on the igbt in the long or short tearm without phase comp. Thanks
