Nice the pros put up some numbers on safety distance. But the CE regulations demand at least 6 mm creepage and clearance distance for class II and 0.4 mm isolation thickness minimum anyway between the mains parts and touchable LV parts.
Even it is DIY and for you own use (and risk), it is wise to comply with this distances for your own and others safety.
Cheers 😉

No fire, no lightning.
Yes, All aproved cottom.
I think there is more fire in the post.
I don´t like some posts. The best will be I will go out/away DIYAUDIO.COM.

Some people dont see DIY electical safety as an aspect of good design. Im different to these, I do. of course I cant make anyone do anything over such a medium as this but I can just ask politely that they inform others of any safety short comings where there are KNOWN to exist. regards A Streeter
about pcb design
In my smps the voltage is 342VDC input (127VAC with doubler) and the output is around (regulation less) +83/-83VDC and there´s not danger enter primary and secondary tensions. I never have problems with safety clearance because 3mm is very good distance. Remember 1mm/air isolation = 1000VDC , ok?
Bye for all

nice work
hi,
Nice work CHACALPOWERS . I was wondering if you could post the schematic of the SMPS. I am also building an smps with sg3525 controller.but mine is 12v to +/-50v 400W.Planning to build a sub woofer amp for car with it.
thanks

regs are real but thouse of us that do this for a living had to start.
my bigest smps does 12kw and semikron tell me that's small.
mains rectified will all ways give a new man a lesson!
and it hearts!
nice to see a toriodal smps tx also i did one and the big boy told me it would not work,it did 😀

Ok Mr. Fibrillator
Thanks by your message. I can post the schematics but remember: this smps 127 VAC input and your project work with 12VDC. I built a 12VDC SMPS input and +60/-60VDC output. I think post pics here in the site.
sorry by my bad english.
Regards.

Hey friend, look my car audio project. It´s a Rod Elliott project based. I like it so much. 12 IRFZ48N, big toroid, SG3524 pwm controller.
Bye.

hello aandy,
can you share some details of the 12kw smps?
i am very curious regarding PFC, cores winding, caps, igbt's, etc
best regards,
