1. A bidirectional energy transmission apparatus, comprising a controller and a bidirectional energy transmission circuit, wherein a control terminal of the controller is connected to a controlled terminal of the bidirectional energy transmission circuit, wherein the bidirectional energy transmission circuit comprises a bidirectional conversion circuit and a direct current-direct current (DC-DC) circuit, a second port of the bidirectional conversion circuit is connected to a first port of the DC-DC circuit, and the controlled terminal of the bidirectional energy transmission circuit comprises a controlled terminal of the bidirectional conversion circuit and a controlled terminal of the DC-DC circuit, and wherein:
the controller is configured to control the bidirectional energy transmission circuit to be in a rectification working state to:
convert, into a first direct current voltage, a three-phase or single-phase alternating current voltage that is input from a first port of the bidirectional energy transmission circuit; and
output the first direct current voltage from a second port of the bidirectional energy transmission circuit; or
the controller is configured to control the bidirectional energy transmission circuit to be in an inversion working state to:
convert, into a three-phase or single-phase alternating current voltage, a first direct current voltage that is input from a second port of the bidirectional energy transmission circuit; and
output the three-phase or single-phase alternating current voltage from a first port of the bidirectional energy transmission circuit.
