A discharge management method, system, and related devices

Abstract

The application discloses a discharge management method, system and related device, and relates to the technical field of electronics. A discharge circuit comprises a power supply end, a first conversion module and a second conversion module. The first conversion module comprises a switched capacitor (SC) circuit and a buck circuit. The power supply end is connected with an input end of the first conversion module. An output end of the first conversion module is connected with an input end of the second conversion module. An output end of the second conversion module is connected with a load. When the load is light, the SC circuit outputs a first voltage to the buck circuit based on a voltage provided by the power supply end. The first voltage is lower than the voltage provided by the power supply end. The buck circuit outputs a second voltage to the second conversion module. The second conversion module outputs a third voltage to the load. In this way, in the light load condition, the voltage of the power supply end can be provided to the buck circuit after being stepped down by the SC circuit, the voltage difference between the two ends of the buck circuit is reduced, and the power conversion rate is improved.
