hy , i want to mmake my own lab power supply using a smps , i want to make 2x12v 2a and 1x5v 1a on secondary. It's my first SMPS and i would like your help to make it . I searched the internet to understand how it works in general , but nothing definitive when it comes to chopper ( how to wind , what materials should i use , what formulas , how to determine secondary current , how thick the wire is going to be and so forth ) . Can you help me with some schematic close to my prefference and the to modify it ?
Also i have some questions for now :
1. Can i take a random ( close to my purpose project) schematic from the internet and wind my chopper according to my needs or should i start with the chopper and then make my final schematic ?
2.I also saw someone who used litz wire , he didnt want to tell me why he used that type of wire instead of a normal wire , after some research i found that is something related to frequency , maybe i am wrong , i am still learning.
