What I am looking for is information that would help me get started on this. While I do know theory behind some of these concepts, I lack the real world experience to tell me exactly what is and what is not possible given the voltage constraints.

Are there prefabricated devices capable of this AC/DC conversion and voltage regulation, or will a bare bones design be necessary? Traditionally, is the AC voltage regulated the rectified, or is it the other way around?

This is a big/long project, so I am not looking for someone to tell me exactly what needs to be done. I just need some guidance on what topics I should begin researching to gain the knowledge necessary to proceed with the project.

Thank you.
