Tahmid,Hi iONic,
Your head is not loosely screwed today. It is tightly screwed and more tightly than average men, because your question is an intelligent one and this sort of out of track ideas/questions are required to learn something intimately.
Yes, a Dc power supply can be converted to AC switching supply. It is as simple as you have said- removing bridge rectifier and capacitor. After removing those from output, you get high frequency AC. Question is, what you will do with that AC? You can do one thing, after removing rectifier and capacitor, if you can filter that with a Low Pass filter to remove modulating carrier frequencies, you can get 50 hertz AC, which will be useful for you. In this way, you can convert that high frequency AC in many pattern for further use. If you do like that, only than removing capacitor and rectifier will be justified.
Thanks for your intelligent question.
