The invention discloses a self-adaptive tracking method for single-phase operation of a three-phase/single-phase bidirectional AC-DC converter, and the method comprises the steps: enabling a first regulator to compare the actual voltage Udc of the three-phase/single-phase compatible converter with a program set voltage reference Udc-ref, generating an overall current reference idc-ref, detecting the temperatures tempA, tempB and tempc of a bridge arm A, a bridge arm B and a bridge arm C, entering a self-adaptive reference distribution algorithm flow, and carrying out the self-adaptive tracking of the single-phase operation of the three-phase/single-phase bidirectional AC-DC converter. The overall current reference idc-ref is distributed to generate current references ia-ref, ib-ref and ic-ref corresponding to the bridge arm A, the bridge arm B and the bridge arm C, and the current of the bridge arm A, the current of the bridge arm B and the current of the bridge arm C are controlled through a modulation module. According to the invention, the three-phase/single-phase bidirectional AC-DC converter is higher in efficiency during single-phase operation, and more power can be saved when a user uses the converter.
