What cause transient on transformer - two switch forward
« on: September 02, 2024, 11:10:52 am »
There is tendency to oscillate with some parasitic capacitence i guess? Any ideas how can i get rid of it?
Thanks =)

At schematic I don't see power source for circuits at right side.

Well, there's an inductor shown. And capacitors (MOSFET Coss, diode Cj).  Is that enough to go on, or--?

That's perfectly normal and happens when the inductor no longer carries DC current. As soon as you add a load, it should stop.
