What are you trying to do exactly ?

220v DC ? Into a transformer wouldn't work very well.

There is plenty of information on the Internet for switch mode power supply designs. Is this for a specific purpose? Any reason you don't want to use a ready made one?

You will get better responses to your posts if you give more information. We don't charge by the word!

I only charge if it's informative or helpful.

Nothing earned so far.

An SMPS fundamentally relies on switching current on and off very quickly (kilohertz). The transistor does the switching.
