I've done a fair amount of work with flyback converters, or minor variants. The other circuit looks like some kind of self-oscillating topology, and I have not done anything with those other than build a Radio Shack kit with one back in the early 1970's.
I really wish manufacturers would provide decent SPICE models for their transformers; I'm cursed with simulating these designs for weeks or months, only to find out they behave so much differently on the bench under load. It's humbling to experience how a converter works so well with no load, only to see it fall to pieces when you put it to work. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
