Zusammenfassung:	The invention relates to the technical field of power supplies, and discloses a control method of a high-efficiency wide-input energy bidirectional flow power supply. When the power supply supplies energy to a load or a power grid, a bidirectional DC/DC converter, a first bidirectional H-bridge converter, a high-frequency transformer module and a second bidirectional H-bridge converter are controlled to enable an energy storage battery pack to output a first DC voltage to a bidirectional DC/AC module, and the bidirectional DC/AC module is controlled to convert the first DC voltage into a firstAC voltage. When the power supply stores energy, the bidirectional DC/AC module is controlled to convert a second AC voltage provided by the load or the power grid into a second DC voltage, and the bidirectional DC/DC converter and the second bidirectional H-bridge converter are controlled to output the second DC voltage to the energy storage battery pack. The scheme can adapt to power supplies input in different specifi
