Typical of me though.always trying the cutting edgeĪnd all this took place around 2001 or 2002. I did not know enough then.Ĭould not get the SMPS Transformer wound correctly. There are literally thousands/millions of these out there still. So much quick switching, so much happening.in the blink of an eye all goes to hell/heaven.
Other things to consider:Ģ.Switching speed(dealing with around 100 Khz here). Think about this: Not your normal Mains transformer running 50/60 Hz that can be wound easily. The Viper software showed how the PCB layout must look. We could not get the Chopper Transformers wound correctly with consistency.
I really don't know what else to say except a more Linear approach ? My SMPS cautions to people are well founded. Still, on any SMPS no matter how brilliant the design, the weakest link is the Main Smoothing Cap. Thinking back now and with all I do daily with cheap TV repairs.well designed SMPS are a boss. Problem is the good ones don't break.so you never get to know them.Īnd the shitty ones you fix all the time become your bread and butter. A "dark art".Ī little caution here from a Dude that has traveled that rocky road. One day I will maybe tell you a story about how you can burn your fingers.Īnd waste money. FWIW.leave SMPS design and everything to pro's.ĭon't go and meddle.
