  "textContent": "Embodiments of this application provide a phase-locking apparatus and a phase-locking method. The phase-locking apparatus includes an amplitude adjustment unit, an amplitude and phase detector connected to the amplitude adjustment unit, a first loop filter connected to the amplitude and phase detector, a second loop filter connected to the amplitude and phase detector, a first oscillator connected to the first loop filter, and a second oscillator connected to the second loop filter. The amplitude adjustment unit, the amplitude and phase detector, the first loop filter, and the first oscillator form a loop; and the amplitude and phase detector, the second loop filter, and the second oscillator form another loop. According to the embodiments of this application, a dual-loop structure of the phase-locking apparatus can weaken frequency coupling between a positive-sequence component generated by the phase-locking apparatus and a negative-sequence component generated by the phase-locking apparatus.",
