Abstract

The invention provides a control method based on a power supply system and a related device, and relates to the technical field of circuit control. The control method comprises the following steps: respectively acquiring current of each bypass circuit; judging whether the current meets a compensation triggering condition or not based on the current of each bypass circuit; and if the compensation triggering condition is met currently, increasing the compensation circuit current corresponding to each bypass circuit to be adjusted to increase the current input to the corresponding load connectingline by the compensation circuit corresponding to each bypass circuit to be adjusted, thereby reducing the current input to the corresponding load connecting line by each bypass circuit to be adjusted, and improving the adjustment precision. Current sharing of the bypass circuits in the power supply system is achieved, the situation that one part of the bypass circuits are fully loaded and the other part of the bypass circuits are not fully loaded is avoided, and the operation efficiency of the power supply system is improved.
