"textContent": "This application provides a voltage control method, an inverter, and a voltage control apparatus, to help improve a response speed and stability of a system. The method is applied to a voltage source inverter. The voltage source inverter includes a bus capacitor, a bidirectional power tube, a filter inductor, and a filter capacitor. The method includes: respectively obtaining a first feedback current and a first feedback voltage from an output end of the filter inductor and an output end of the filter capacitor; obtaining a first duty cycle and a second duty cycle based on the first feedback current, a maximum current reference value, and a minimum current reference value in a current loop; obtaining a third duty cycle based on the first feedback voltage and a voltage reference value in a voltage loop; and selecting one of the first duty cycle, the second duty cycle, and the third duty cycle, and controlling the bidirectional power tube, so that a duty cycle of the bidirectional power tube is between the first duty cycle and the second duty cycle.",
