So, I was designing this basic High-Power Buck converter (12 V * 20 A) and I was testing how it should theoretically work in reality. However at random moments and without a clear hint it just throws out errors about transient point not converging, and the assistant does not really help at all. This is why I'm asking the help of this forum to help, and if you all are willing to explain me what I did wrong (assuming I did of course, which is very likely possible considering I'm just a student)
The schematic is included with this page so you all can toy with it and understand what I don't. I tried everything.
