Abstract
A multi-level converter control method is provided that includes: acquiring an inductive current of an LC filter in a driving pulse period; determining a to-be-adjusted first switch tube and a first duty ratio adjustment amount of the to-be-adjusted first switch tube based on a slope of a rising period of the inductive current, and adjusting a duty ratio of the to-be-adjusted first switch tube based on the first duty ratio adjustment amount; and determining a to-be-adjusted second switch tube and a second duty ratio adjustment amount of the to-be-adjusted second switch tube based on a slope of a falling period of the inductive current, and adjusting a duty ratio of the to-be-adjusted second switch tube based on the second duty ratio adjustment amount.
