Recently, I have been learning the mathematical modeling of switching converters. Looking for a lot of data, I know that the current loop control mainly includes peak current, valley current and average current control methods. The detailed process of peak current modeling is found in the book "modeling, control and digital realization of switch converter". However, my brother has not found the detailed introduction of average current modeling. I would like to ask you brother and sister have any good information recommendation, the best is books (the most detailed explanation). Thank you very much!

Hi, one of the best power electronics modeling books is the following: Fundamentals of Power Electronics, second edition by Robert W. Erickson and Dragan Maksimovic. Ch. 12 is about current programmed control and derives both a simple first-order model and a more accurate model. To more efficiently read and understand Ch. 12, I recommend to read Ch. 2, Ch. 7, Ch. 8, and Ch. 9. Hope this helps, Antonino
