Beschreibung
Zusammenfassung:	The present disclosure discloses a T-shaped three-level overload operating system, including a three-level topology and an overload mode switching system. The topology is connected with a first device group and a second device group which form a T shape; the first device group is designed with an overload capacity, and the second device group is designed with a rated capacity; and the overload mode switching system is configured for being connected to the topology to control the first device group to perform overload two-level operation on the topology, or to control the second device group to perform normal three-level operation on the topology, so that the number of device groups of the overload design can be effectively reduced, and then the cost of the system can be reduced. A working method of the T-shaped three-level overload operating system is further disclosed. The topology can be rapidly switched among working modes according to an output current of the topology.
