POWER SUPPLY CIRCUIT AND ENERGY STORAGE DEVICE

Abstract

A power supply circuit includes a DC/DC conversion module, first/second AC/DC conversion modules, an alternating current input interface, and first/second alternating current output interfaces. A first end of the first AC/DC conversion module is connected to a battery module through the DC/DC conversion module, a first end of the second AC/DC conversion module is connected to the first end of the first AC/DC conversion module through a direct current bus, the first alternating current output interface is connected to a second end of the first AC/DC conversion module and a first terminal of the alternating current input interface, the second alternating current output interface is connected to a second end of the second AC/DC conversion module, both the first and second AC/DC conversion modules may operate in a rectification mode or an inversion mode, and the DC/DC conversion module operates in a discharging mode or a charging mode.
