Zusammenfassung:	The utility model discloses a grid-connected off-grid integrated device for a microgrid wind-driven generator. The grid-connected off-grid integrated device comprises a control circuit, a three-phase rectification circuit 1, a three-phase rectification circuit 2, a DC/DC power supply 1, a DC/DC power supply 2, a manual switch, and a protection circuit. The grid-connected off-grid integrated device has beneficial effects that after acquiring electricity from the wind-driven generator, the grid-connected off-grid integrated device for a microgrid wind-driven generator performs off-grid and grid-connected operation so as to decrease intermediate links, save cost, and highly-efficiently use energy, and that a microgrid wind-driven power generation system or wind-photovoltaic complementary microgrid power generation technology can be achieved just by one draught fan, one grid-connected off-grid control integrated device, and two inverters.
