Ah, I see. Thanks for the clarification!

So I decided to go with the 2.7c as I highly doubt I'll be pulse-skipping any time soon.

Now it's time for the MMC. I have been thinking of buying WIMA MKP1T031006B00MSSD capacitors (100nF; 1.6kVDC; 1,4kV/μs). I have found only one datasheet and unfortunately it's in German, but here it is: https://www.tme.eu/Document/c9c3612d9384576529f461ace7f3add8/WIMA_MKP_10.pdf
I think they should be absolutely fine in a 300A max. MMC. But before I buy anything, I'd like to hear from you guys if these are a good choice.

So as always, thanks in advance!

David

Thanks for your replies! You really cleared things up for me

A few more questions that came to mind:

- My SSTC was based on the IR2153 ic which has a built-in dead-time, so things were simple. What I don't understand is how do Steve Ward's drivers achieve dead-time? I can't figure it out from the schematic. Also, when coilers show output of the inverter on a scope, there also seems to be no dead-time (?), but there has to be some, right? What am I missing?

- What would be the max peak current that those IGBTs could handle? If I understand correctly, it mostly depends on the max power the device can dissipate, but how exactly do I calculate it based on that?
Datasheet (https://www.tme.eu/Document/dbf1ac2316f96cbe820db95a21100319/DGTD65T60S2PT.pdf) lists 428W@20*C and 214W@100*C

- Do I need 2 GDTs for a full-bridge or can I use 1 with 5 windings? Some Universal Driver schematics I've seen have outputs for 2 GDTs and I'm a bit confused.

- Is the design of the GDT critical? Could someone recommend me a good and easy to follow GDT design guide?

As for the doorknob caps: I was interested in using them because I've seen styropyro use them in his VTTCs and in his HFVTTC so I assumed that they would be suitable for a DRSSTC. But I will buy some regular PP caps if no one can confirm my assumption.

Sorry for all those questions, they're probably really trivial, but I want to avoid as many dumb mistakes as possible

Thanks
David
