Abstract
This application discloses a common-mode voltage adjustment method and apparatus, and a control system, and relates to the field of electronic technologies. In an example method, a controller generates an injection instruction of a first common-mode voltage based on a first modulation scheme, generates an injection instruction of a second common-mode voltage based on a second modulation scheme, and generates an injection instruction of a third common-mode voltage based on the injection instruction of the first common-mode voltage and the injection instruction of the second common-mode voltage during a modulation scheme switching period. The injection instruction of the third common-mode voltage may be used to control a inverter circuit to output the third common-mode voltage.
