AC-DC CONVERTOR PWR BOARD DESIGN

[rinj]

Dear all,
this question is to experienced power electronics circuit designers.
I have to design a PCB layout for 115ac to +28/+15/+5vdc .
The circuit contains,
1. Fuse and Inrush current protection ckt
2. EMI Filter
3. LC filter
4. Bridge rectifier and DC capacitor
5. Flyback transformer
6. Current Sense Conditioning Ckt With Isolation
7. Isolated constant current feed back for the controller etc......
The current for the nets pass arnd the board is below 1A.
Can anybody please explain to me the design guidelines summary, mainly for Electrolytic capacitors (22/10 MF, 25V), transformers & MOSFETS (600V/0.8A)

(I have only less experience in power electronics. I went throgh the datasheets and many design guidelines from the internet. )

Please help me experts.
thanks,
rinj

The easiest is if you post the layout that you have created and we comment on it. Otherwise we will just go on forever, trying to explain this and that should be close to such and such.
So please post your design. That way we get an idea about your component sizes, space constraints, etc.

Hi rinj !

The best way to start design is to look at application notes of
semiconductor producers, like Texas Instruments, ON Semiconductors,
Siemens - Infinion .

Some good examples (also PCB layouts ) you will find on

you mean you have to lay it out...or design it?

rule of layout = keep current loops small as possible....especially fast ones with edges .

but you say you are beginner and i point you to the powerintegrations powerint.com website and they help you with their own forum too.

so as long as you dont have massive power....powerint.com is for you

Thanks for all. I checked the links
I may come up with more questions when my design progress.
