power supply DC design

[Shreehari]

I am asked to design my own powersupplies of voltages 15/-15V and variable one 0-5V .The onput to these are 230V AC.How can I start this project.what are the concerns that I should hav while designing?how can I design this ?Pls help me.

 

[srizbf]

following parameters are to be considered.

-input voltage variation
-output regulation
--linear or switched

if linear, design will be simple but efficiency will be low.
for a bench power supply these things are minimum .

Refer the book

"Fundamentals of Power Electronics By Robert Warren Erickson, Dragan Maksimoviæ""

Finding a hardcopy must be difficult, but the softcopy is available in books.google.co.in

https://books.google.co.in/books?id...rce=gbs_book_similarbooks#v=onepage&q&f=false

Very nice book....

 

[srizbf]

national /texas and many others have published app notes on this .

one that you can refer for initial idea is:

http://www.fer.hr/_download/repository/Linear___Switching_Voltage_Regulator_Handbook_(ON_Semiconductor).pdf

but that link not working...

 

[srizbf]

you have just clicked the link.

since it is very long , at the end there is 'ON_semiconductor.pdf' which may not be passed on.

copy the entire line to a page and then get .
