POWER CONVERSION SYSTEM (PCS) PARALLEL ARCHITECTURE AND SYNCHRONIZATION CONTROL METHOD THEREOF

The application discloses a power conversion system (PCS) parallel architecture and a synchronous control method. Among a plurality of corresponding PCS controllers of the PCS parallel architecture, when a target PCS controller is the first to issue a synchronization signal on a synchronization signal bus, the target PCS controller obtains control authority, the synchronization signal issued by the target PCS controller is taken as a system synchronization signal, and other PCS controllers that did not obtain control authority refer to the system synchronization signal for synchronizing with the system synchronization signal.
