Abstract: The present disclosure provides a method for controlling a power adapter and a power adapter, and relates to the field of power technologies. The method includes: obtaining a real-time value of a bus voltage of the power adapter; matching the real-time value of the bus voltage with N control voltage intervals V1 to VN to obtain a real-time control voltage interval that matches the real-time value of the bus voltage, wherein N≥2, the N control voltage intervals are continuous and incremental from V1 to VN, and the N control voltage intervals V1 to VN correspond to N different output power control values P1 to PN; and adjusting, according to the real-time control voltage interval, an output power command value of the power adapter to an output power control value corresponding to the real-time control voltage interval.

Abstract: The present disclosure relates to a hot-plug protection method and a power supply device. The method includes, when the connection status between the power supply device and the to-be-charged device is detected as disconnected through the detection pin, turning off a switch assembly within a first time period, where the switch assembly is connected in series between the voltage converter of the power supply device and the connection port, and maintaining an output voltage of the voltage converter at a first level within a second time period, the first time period being shorter than the second time period.
