Abstract: An apparatus, method and system for adjusting a voltage stabilization output of a power source (10). The power source (10) forms an output voltage based on a supply current. The apparatus includes a sampling module (11), a PID adjustment module (12) and a control module (13). The sampling module (11) is configured to sample the output voltage of the power source (10) to obtain a sampled voltage (S100). The PID adjustment module (12) is configured to obtain a switching frequency signal by PID control adjustment based on the sampled voltage and a preset control parameter. The PID control adjustment includes a voltage loop control adjustment and a voltage-difference-change-rate loop control adjustment (S200). The control module (13) is configured to form the supply current according to the switching frequency signal (S300). The voltage stabilization output of the power source (10) can be realized.
