This application discloses a method for dedicated data transmission and synchronization signal sharing in intelligent power cabinets, belonging to the fields of high-power power electronics technology and industrial communication. This method modifies the UART protocol frame structure, expanding the start bit from 1 bit to 3 bits to distinguish between A, B, and C phase synchronization signals or no synchronization trigger, allowing the phase information of the synchronization signal to be directly embedded in the data communication frame.

This method improves the synchronization accuracy, current sharing performance, and system reliability of multi-cabinet parallel systems, and supports dynamic redundancy switching in case of synchronization source failure.
