We are back on SMPS again
Flyback, I really don't know. My experience with SMPS is based solely on my experience with CRT SMPS. Nothing else.
You see, I can and only will comment on what I know.
People might say SMPS are all different...different designs....different applications etc, etc, etc.
And they are all 100% spot on.
No matter what designers of SMPS think up in the future....I really have no time for them (SMPS).
Unless they are designed by the Masters of that black art...like professionals Delta Electronics.....
I even dabbled with a SMPS design years back. I ordered 100 Viper 50 IC's from America.
My Chopper Transformers were wound and built in New Zealand.
The boards were designed and etched by me right here in South Africa.
I received my Vipers. I received my Choppers. My boards and parts were all here.....
Out of I think four assembled units...only ONE worked properly. It never blew up when the others did???
It could handle what the others could not.
After wasting/blowing up 6 of my Vipers, I stopped. No point in wasting to prove a point if you really don't know the in's and out's of what you are doing...you can read all you want about SMPS....I followed the rules to the letter...and failed.
ST had simulation. They had all the advise on the NET....no go.
Dark Art.....
Different scenario.......People involved and wise to SMPS design..it was all they needed. Many, many Vipers are out there still..found in DVD players and other goods. I have not seen many 50's here though....I believe I still have around 90+ in storage.
So, for me, to repair SMPS is part of my daily job....design and build is another animal altogether
