1. An apparatus for adjusting a voltage stabilization output of a power source, wherein the power source forms an output voltage based on a supply current, and the apparatus comprises a sampling module, a PID adjustment module and a control module, wherein:
the sampling module is configured to sample the output voltage of the power source to obtain a sampled voltage;
the PID adjustment module is configured to obtain a switching frequency signal by PID control adjustment based on the sampled voltage and a preset control parameter, wherein the PID control adjustment comprises a voltage loop control adjustment and a voltage-difference-change-rate loop control adjustment; and
the control module is configured to form the supply current according to the switching frequency signal.
