I understood him fine. He wants to construct a circuit to do the rectifying and with added voltage regulation, and wanted a diagram.
We shouldn't be so hard on people who have imperfect English skills, that is unfriendly. The OP used correctly spelled terms "rectification" "voltage regulator" and "diagram" which is probably a lot better than we could have done trying to post a question in his native language.
Now we probably lost the OP so non of it matters...
