design&simulation of electronic ballast

[remyatr]

i would like to deign an electonic ballast for flourescent lamps.i would like to include a buck boost power factor correction circuit for the improvement of powerfactor. a series resonant parallel loaded circuit is used to drive the lamp output stage.i would like to switch the circuit using zero voltage switching and i would like to sense the output voltage and according to the change in out put voltage i have to adjust the puls width of the two switches inorder to achieve both same phase for both input volage and current.My circuit is attached below..how can i design such an electronic ballast and how i simulate the same?

hi, man.
i suggest you to search paper on:
PFC using buck-boost
and
LCC resonant converter.

the application note whitch publiced by IR,Fairchild,ST,Philips...

hope may do some .

howcome you choose buck boost with its chopped input current.?

you can get low voltage out but for fluorescent you need high voltyage
