This work presents an overview of distributed submodule power electronics based on resonant and switched-capacitor topologies configured in a ladder architecture. We present a new resonant switched-capacitor topology, termed a `direct conversion' topology because current flow is always uni-directional in the inductor component. The direct topology can be seen as a resonant version of the more common 3-level buck converter. We discuss some of the relevant theory for the direct topology compared… CONTINUE READING
