Thanks everybody for the help. Actually the project has been assigned
to me by a very strict instructor of mine, so I can't tell her that
its trivial or very hard etc etc. Also nothing else has been
specified. As far as I understand I have to use TRIACs to design a
variable voltage/frequency source, but thats the only thing I know.
Can anyone suggest me a site or something from where I can get atleast
a circuit diagram or the components to be used to design such a
circuit.
There's a basic treatment of the topic in a ST Micro applications note
where they cover several triac topologies and problems they may have.

Thanks Mark, the document really helped me. That was the thing which I
needed. Lots and lots of thanks again.



Also take a look at some thyristor triac scr databooks circa 1970's in
your campus library if they have any, the application notes should have something.
