Claim 0:
1. A power network flexible closed-loop controller topology shared by modules, wherein each single-phase topology comprises:
an AC/AC (Alternating Current/Alternating Current) converter comprising N1 CHB (Cascaded H-Bridge) modules, and an AC/DC (Alternating Current/Direct Current) module comprising N−N1 full-bridge rectifiers;
AC (Alternating Current) input terminals of the N1 CHB modules are connected in series to form an AC (Alternating Current) port on one side of the AC/AC converter,
AC output terminals of the N1 CHB modules are connected in series to form another AC port on an other side of the AC/AC converter,
AC input terminals of the N−N1 full-bridge rectifiers are connected in series to form an AC port of the AC/DC module, the AC port on the one side of the AC/AC converter is connected in series with the AC port of the AC/DC module and then connected to a first AC network, the another AC port on the other side of the AC/AC converter is connected in series with the AC port of the AC/DC module and then connected to a second AC network, and an AC incoming line and an AC outgoing line of three-phase topology are connected to the first and second AC networks in a star connection mode, wherein N and N1 are positive integers and N is more than N1.
