Abstract
A multi-level converter includes a plurality of capacitors coupled in series between first and second nodes of a DC port and coupled to one another at n−2 first intermediate nodes. The converter also includes a switching circuit including at least one first switch configured to couple the first node of the DC port to an input/output node, at least one second switch configured to couple the second node of the DC port to the input/output node, and at least three third switches configured to couple respective ones of the first intermediate nodes to the input/output node. The converter further includes a control circuit configured to control the first, second and third switches to provide an n-level converter.
