The invention relates to a looped network type multi-terminal AC/DC power distribution system adapted to access of a high-power electric vehicle, and the system comprises a plurality of groups of medium-voltage AC power supplies and corresponding medium-voltage AC/DC energy routers, and a plurality of groups of low-voltage AC power supplies and corresponding low-voltage AC/DC energy routers. The first direct-current bus is of an annular structure, the first direct-current bus and the second direct-current bus each comprise a positive bus, a zero bus and a negative bus, an alternating-current load is connected to the first direct-current bus or the second direct-current bus through the AC/DC converter or connected with the alternating-current bus through the alternating-current transformer, and the direct-current load is connected to the first direct-current bus or the second direct-current bus through the DC/DC converter. The load is connected with the positive bus and the zero bus, or the positive bus and the negative bus, or the zero bus and the negative bus of the direct-current bus, and the first direct-current bus is connected with the second direct-current bus through the direct-current bus switch. Compared with the prior art, the method has the advantages of meeting the multi-voltage-level and large-scale electric vehicle access requirements and the like.
