Could any one help me out regarding the attached transformer zip files.

What kind of these transformer & where to used it & Where to get these type of transformer.
 

Looks like a torroid transformor used in tube light ballast. As you can see, there are just 3 simple windings. Guess you can do it yourself. You'll get the core with any component or ferrite core vendors. Cheers.

Thanks Pranam,

Could you able to explain me what is need of these type of transformer ? What is the principle behind it ?
 

If you see at the snap, these toroid transformer has 3 winding. One winding having 2 turns & other two are having three turns. How it works & how to design it.
Could you tell me anyone how to recognize the Py & Sy one.
 

The torroid transformor is a part of the oscillator which triggers the base's of the 2 transistors to start and run the oscillator. The windings connecting to the base of the transistor's may be considered as primary whereas the coil which connects the the tube may be considered as secondary. Hope going through these below links will enhance your knowledge regarding the same....Cheers
