double two transistor forward

hi all
can you help me?
i want design double switch forward that input voltage was 230(+10%;-15%)v:
output voltag was 12±1% v;output current was 20A ;
this switch should be controlled by IC SG3842;
if you knew which book is good for this desine ;that is very good for me.
thanks a lot
rajabi
 

sg3842+application note

Start with a google search on "two transistor forward converter design"
and you will find quite a bit.
https://www.google.com/search?hl=en&lr=&q=two+transistor+forward+converter+design&btnG=Search

Take a look at this application note for example
www.fairchildsemi.com/an/AN/AN-7004.pdf

Study the section on the two-transistor forward converter and see what
devices are being used and then you might want to browse more application
notes and I am quite certain you will find enough information to put
together a design.

Best regards,
\[v_c\]
