Elektor has been the top electronics hobbyist magazine for many many years and has 1000s of example circuits.
I have set the start page to searching for example circuits, in particular, to 'Power Supply' circuits. Change it in the search options to find other types of electronic circuit examples.
Magazines - ELEKTOR.com ? Platform for electronics and microcontrollers
Need to register but can then download 3 complete articles as and when you wish for free as PDFs.
Warnings:
Working on mains power projects can be dangerous and requires that you have a good background in electrics and electronics.
Mistakes can lead to sudden overheating, explosons and fires.
