Title:
CIRCUIT, AC/DC CONVERSION MODULE, DIRECT-CURRENT MICROGRID AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/113932
Kind Code:
A1
Abstract:
Provided are a circuit, an AC/DC conversion module, a direct-current microgrid and a control method therefor. Further provided are a control device for a direct-current microgrid, and a computer-readable storage medium. The circuit comprises: a pair of output ends, N pairs of input ends, and a switch group electrically connected to the pair of output ends and the N pairs of input ends, wherein the pair of output ends is configured to electrically connect to a load or a direct-current bus; the N pairs of input ends are configured to electrically connect to N pairs of output ends of N AC/DC converters one by one; and the switch group is configured to selectively connect AC/DC converters electrically connected to the N pairs of input ends to a circuit loop in a series connection, parallel connection or series-parallel connection form. By means of the embodiments of the present disclosure, the problem in the related art of the stability of AC/DC converters in series-parallel connection being low is solved, thereby improving the stability of the AC/DC converters in series-parallel connection.
