Need help with this circuit.

[Jaseelmj]

Plz any one could help me with this dc to dc converter circuit.i am a electronics student and i chose this circuit for my project.
Could anyone tell me its working?
What is the use of small circuit in bottom left?

The circuit is far too complex for you.

Where are you going to get the transformers ??????

I am still searching for it..no idea from where i will get.
Could you please help me with this??

You want to copy a circuit for your project? Try a simple one like an Audio amplifier, or a clock. This IS NOT a circuit for implementation by novices.

This is our miniproject.not main.
For getting max marks we have to select a circuit bigger..and have to be accepted by the tutor..
Please help us with this..its kind of urgent

Since you are simply copying a circuit that might not even work, then I guess you are not learning how to design an electronic circuit. Then are you simply learning how to ask on a forum where to gather parts and solder them together?

Actually i selected electronics eng with a great passion for it..how these things works
Bt i have to complete this project..no time to learn from the beginning..
I have been trying to learn about this circuit for last month..learning each and one components..bt couldnt understand in a whole
Thats why i thought of this..if someone helps that would be a great help.
I jst have some doubts..if someone could help me with that..

It looks like an ancient (and inefficient) design, since nowadays there are ICs which handle the FET driving more elegantly. The transformer is crucial to the success/failure of this circuit. The specified FETS appear to be obsolete.
The small circuit at bottom left is for turning the 12V supply to the inverter on/off remotely.

Modify your "small" project.
