Power Supply Design Information

[Saitama]

Hello! I've taken an interest in designing power supplies, but they are simple, non reliable and overall bad, so I want to do a bit of research on this topic to improve my designing skills. What books, papers, videos and other kinds of information do you suggest?
Thank you for reading my thread and I will appreciate all replies
