    摘要: A converter system includes a first converter, a second converter, and a first inter-phase transformer. The first converter is electrically connected to the second converter in parallel between a first input terminal parallel end and a first output terminal parallel end. The first inter-phase transformer is disposed at the first input side parallel terminal or the first output side parallel terminal, and the first inter-phase transformer is operable to restrain a circulating current generated by the first converter and the second converter.

    摘要: A control method of a converter system includes: sampling a current of each three-phase winding to obtain a real-time current of each converter; obtaining a mean current by averaging the real-time current of each secondary converter and the real-time current of the primary converter, and transferring the mean current to each secondary converter; obtaining the differential-mode current corresponding to each secondary converter according to the mean current and the real-time current of each secondary converter; performing a circulation current control on the mean current and the differential-mode current of each secondary converter based on a d-q coordinate system to generate a mean-current conditioning signal and a differential-mode current conditioning signal, thereby controlling each secondary converter; and obtaining a sum of the differential-mode current conditioning signal of the secondary converters and negating the sum to obtain a differential-mode current conditioning signal of the primary converter, thereby controlling the primary converter.
