I have learned enough to build a few of these. I want to improve it with a better IC, higher frequency and gate drivers. Forget the hall wiper, I have gone to a convention wiper pot of my own fabrication so the trigger has feel and the start voltage does not effect the final trigger position. (left side of diagram is the "hall wiper") I don't have a non pdf diagram of the new version handy.
here is a short video of it working.
I just want to improve it as a learning exercise.
People say the LM324 cant drive the SUP90 P fets yet it works at least at 470hz. No heat and the wave form seems pretty square at the gates.
I have an LM339 oscillator with adjustable frequency set up but, I am looking for suggestions on the gate drive.
any and all suggestions are welcome.
