Power supply adjusting apparatus

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;
• and
• a tracked signal frequency division processing unit, adapted to divide the received tracked signal into a high frequency signal and a low frequency signal according to a preset policy, wherein the low frequency signal is sent to the voltage adjustment controlling unit;
• and
• a precise tracked voltage correcting unit, adapted to:
• adjust the voltage outputted by the voltage adjustment controlling unit according to the high frequency signal outputted by the tracked signal frequency division processing unit, and output the adjusted voltage.
