Abstract

See full text

An inverter control method, apparatus, and system are provided. The method in the embodiments of the present invention includes obtaining power distribution line graph of an inverter switch according to an output power and an input voltage that are of an inverter; when an area to which the inverter belongs is a first area and the inverter switch works at a second frequency, switching the inverter switch to a first frequency; and when the area to which the inverter belongs is a second area and the inverter switch works at the first frequency, switching the inverter switch to the second frequency. In the embodiments of the present invention, whether a working frequency of an inverter switch needs to be changed is determined according to an output power and an input voltage, which improves control efficiency, thereby effectively improving conversion efficiency of an inverter.
