Abstract

The invention discloses a power network flexible controller topology shared by modules. Each single-phase topology comprises an AC/AC converter including N1 CHB modules, and an AC/DC module including N−N1 full-bridge rectifiers; the AC input terminals of N1 CHB modules are connected in series to form an AC port on one side of the AC/AC converter, the AC output terminals of N1 CHB modules are connected in series to form the AC port on the other side of the AC/AC converter, the AC input terminals of N−N1 full-bridge rectifiers are connected in series to form the AC port of the AC/DC module, the AC port on one side of the AC/AC converter is connected in series with the AC side port of the AC/DC module and then connected to a first AC network nd the AC port on the other side of the AC/AC converter is connected in series with the DC side port of the AC/DC module.
