Need some help understanding an SMPS or this specifcally
Does anyone got any idea how to analyze an SMPS simply? I already know that the TOP245YN there does the oscillation quickly for the primary side of the transformer (chopper) right there. But the rest of it, I'm not sure, especially the secondary side. And that, this is a full bridge rather than a half bridge design (judging by that rectifier up there and how not two large capacitors are in series together).
What common parts here that'd likely to fail over time or suddenly? my guess would be those diodes that'll cause the TOP245YN to shut down. I'm also guessing that this is a 40W or 85W supply. Not really sure though, besides the datasheet of that. Maybe its 85W since this is on a metal chassis with some thermal grease on. And that, we have an average of 220-240v around here.
I don't wanna be ignorant about anything like this (hopefully same as you guys being arrogant), especially that this is a high voltage. I got used to using linear transformers for my designs and its time to up my game a bit.
Any suggestions or recommendations will be greatly appreciated. Thanks everyone!
