Abstract

A new digital average-current-mode controller for converters operating in continuous conduction mode is introduced. The principal idea of the proposed control scheme is to estimate the required value of the duty ratio based on the dynamic of the converter using the measured samples of current and voltage signals. The proposed control scheme is stable for any value of the duty ratio without employing an external ramp. Furthermore, it is robust, accurate, and has a fast dynamic response.
