This application discloses a Vienna rectifier, a Vienna rectifier control method, and a charging pile, and relates to the field of circuit technologies. The Vienna rectifier includes a three-phase rectifier circuit and a controller. When a voltage phase of an ith-phase rectifier circuit of the three-phase rectifier circuit precedes a current phase of the ith-phase rectifier circuit by a first angle, the controller controls a switch of the ith-phase rectifier circuit to be turned on within a second angle after a voltage of the ith-phase rectifier circuit reaches a zero crossing point, where the second angle is greater than or equal to the first angle; and when the current phase of the ith-phase rectifier circuit of the three-phase rectifier circuit precedes the voltage phase of the ith-phase rectifier circuit by the first angle, the controller controls the switch of the ith-phase rectifier circuit to be turned on within a third angle before the voltage of the ith-phase rectifier circuit reaches the zero crossing point, where the third angle is greater than or equal to the first angle, and i=1, 2, or 3. The Vienna rectifier provided in this application supports reactive power adjustment, improves practicability, and reduces hardware costs of the charging pile.
