Abstract

The present disclosure relates to a switched-capacitor converter comprising: a first terminal; a second terminal; a switched-capacitor ladder network comprising a plurality of serially connected first capacitors defining a plurality of flying capacitor nodes; a plurality of serially connected second capacitors defining a plurality of output capacitor nodes, wherein nodes of the flying capacitor nodes can be connected to nodes of the output capacitor nodes in a plurality of ladder converter configurations to perform a switched-capacitor ladder power conversion; and a switch matrix configured to connect the first terminal to different flying capacitor nodes and/or configured to connect any flying capacitor node to any other flying capacitor node or output capacitor node10 according to different switch configurations according to different switch configurations. The disclosure further relates to a switched-capacitor converter assembly comprising a plurality of serially and/or parallel connected switched-capacitor reconfigurable switched-capacitor ladder converters. The disclosure further relates to methods for converting an input into an output voltage using a switched-capacitor converter and for operating an assembly of switched-capacitor converters.
