A bidirectional energy transmission apparatus (30) is disclosed, including a controller (303) and a bidirectional energy transmission circuit (300). A control terminal (303a) of the controller (303) is connected to a controlled terminal (303c) of the bidirectional energy transmission circuit (303). The controller (303) is configured to control the bidirectional energy transmission circuit (300) 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 (300a) of the bidirectional energy transmission circuit (300), and output the first direct current voltage from a second port (300b) of the bidirectional energy transmission circuit (300). Alternatively, the controller (303) is configured to control the bidirectional energy transmission circuit (300) to be in an inversion working state, so as to convert, into a three-phase or single-phase alternating current voltage, a first direct current voltage that is input from a second port (300b) of the bidirectional energy transmission circuit (300), and output the three-phase or single-phase alternating current voltage from a first port (303a) of the bidirectional energy transmission circuit. The controller (303) controls the bidirectional energy transmission circuit (300) to be in different working states, so as to implement bidirectional conversion from the three-phase/single-phase alternating current voltage to the direct current voltage, so that configuration is flexible.
