Abstract: Example bidirectional energy transmission apparatus and methods are described. An example of a bidirectional energy transmission apparatus includes a controller and a bidirectional energy transmission circuit. A control terminal of the controller is connected to a controlled terminal of the bidirectional energy transmission circuit. In the example, the controller is configured to control the bidirectional energy transmission circuit to be in a rectification working state, so as 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. The controller is configured to control the bidirectional energy transmission circuit to be in an inversion working state, so as to convert, into a three-phase or single-phase alternating current voltage.
