Abstract: This application provides a power rectification method and apparatus, to supply power to a load by using a power supply capacity gap formed by a communications power that is at an existing network site, thereby achieving a capacity increase. The method includes: obtaining a total input current of each of three phase lines; and when it is determined that a total input current of at least one of the three phase lines is greater than a total input current threshold corresponding to the at least one phase line, adjusting a rectifier connected to the at least one phase line to reduce a total input power of the at least one phase line, so that the total input current of the at least one phase line is less than or equal to the total input current threshold corresponding to the at least one phase line.

Abstract: This application relates to the field of communications technologies, and discloses a backup power supply control method, to obtain target power supplying duration of a battery, and determine average power consumption of a communication station (101) within a time period corresponding to the target power supplying duration. Further, a state of charge of the battery is obtained, and actual power supplying duration for the battery to supply power to the communication station (101) is determined based on the state of charge of the battery and the average power consumption. Therefore, an operation mode of a communication device in the communication station (101) may be adjusted, to reduce the average power consumption of the communication station (101) within the time period corresponding to the target power supplying duration.
