The invention relates to the technical field of power electronics, in particular to a feedback type source-load integrated system capable of working in multiple modes, which comprises an AC/DC module capable of bidirectionally flowing energy, N isolated DC/DC modules capable of bidirectionally flowing energy and N DC/AC (DC) modules capable of bidirectionally flowing energy, and is characterized in that N is a natural number; the DC/AC (DC) with the energy capable of bidirectionally flowing performs DC-AC conversion or DC-DC conversion by changing a control strategy. The system works in a source mode to increase the power and increase the working voltage range; when the system works in an on-load mode, the load capacity is expanded, the bearable voltage of the load is increased, the output energy of the product is fed back to a power grid through the feedback type source-load integrated system, and the energy consumption can be effectively reduced; the system works in a source load mode, which is equivalent t
