UCC21520 and/or UCC27321P schematics?
« on: March 17, 2023, 06:29:37 PM »
Looking for a better way to drive my IGBT bricks at way more than 30kHz, ACNW3190's just won't cut it. they're too slow. Trying to drive bigger ferrite transformers with about 350V output of my full bridge, with 5 turns of primary in my ferrite cores (to draw like 20A), and they need more than 30khz to drive.

So I bought these UCC chips, 21520's arrived and 27321's on the way today. Does anyone have a schematic for them? (As long as it outputs AC signal, either to drive +15V and -15V into my gates to avoid cross conduction or drive a GDT into them)

I would look at the documents of them on the texas instruments site, but not sure which schematic is better
I'm Trent and deaf. I like high voltage and try to make better YouTube content. Also a survivor of a PT explosion.
