The Mega SMPS Design Cheat Sheet!
To stop bumping that old thread, and because i have made significant improvements to the spreadsheet, i decided to post it in a new one.
I have added half bridge and full bridge calculations. And there's LOTS more goodies to come, i'm just getting started. What i promise you is that there will be MORE variables, like voltage drops of transistors and diodes, to provide the best possible accuracy. And there's more... but i'll keep it a surprise for the time being.
There will also be more tips on snubbers and voltage spike elimination devices, as once you have a working supply, lowering its noise level is the next challenge. I'm also working on a fresh-out-the-oven low power split supply of my own design for use in standby/driver circuits for half- and full bridge supplies. Say no to flimsy and expensive IC drivers - with a bipolar driver supply, a small and easy to make gate drive transformer is all you need to drive ANY configuration of switching devices.
And beyond this, i also have real life and school to attend to... I'm a busy guy.
PS. You know, it occured to me that there's no "SMPS for Dummies" book. I might just write one someday.

It's comprehensive but it's got too much math for a dummy to understand... and some of the results of the equations are pulled out of the blue with no explanation on how he got there. It's a good book (especially the chapter on control loop compensation), but there are easier ones.
I did the math so YOU don't have to.
