Universal half-bridge driver
profdc9, Tue Dec 19 2017, 05:49PMI laid out a circuit board for the half-bridge driver I designed that uses a gate driver transformer, the one in this document:
A picture of it is below. When I get some time I'll build it up and test it. It uses the UCC37321 so it should be able to drive decently powerful IGBTs, and possible SSTC and induction heaters and the like with an adjustment of frequency.

Quite a nice document you've put together. I look forward to seeing your new board in operation.

It already works. I built it on perfboard and it works fine. I am laying out a circuit board because wiring it up by hand is a pain.
I reduced the board size to save some fabrication money and space. The latest is below. I added an LED that flashes when the overcurrent condition occurs, and a way to externally disable the gate driver, so that for example you could turn it on and off to make a musical SSTC.
