Abstract:
1. A power supply adjusting apparatus, comprising: a primary isolation converting unit, connected to an input of a power supply and adapted to: convert voltage or current of an input power supply signal from the input of the power supply, and output a power supply signal that meets an expected voltage or current requirement; a voltage adjustment controlling unit, adapted to: determine an adjustment control signal with respect to the output voltage according to an expected output voltage and a tracked signal provided by a powered apparatus, and output the adjustment control signal; and a secondary non-isolation adjusting and converting unit, connected to an output of the power supply and adapted to: adjust the power supply signal outputted by the primary isolation converting unit according to the adjustment control signal outputted by the voltage adjustment controlling unit, and output an adjusted power supply signal; wherein the voltage adjustment controlling unit is placed in the powered apparatus and implemented by a core processing unit of the powered apparatus and outputs a voltage to the primary isolation converting unit and/or secondary non-isolation adjusting and converting unit, and the powered apparatus further comprises an adjustment requesting unit, adapted to receive an adjusted power supply voltage signal and output an expected voltage adjustment parameter to the core processing unit.
