Abstract
This application provides a power converter and its control method, control device, and storage medium, relating to the field of power electronics technology. The power converter includes: a power conversion circuit having an output inductor; and a controller for controlling the inductor current of the output inductor within a specified current range when the power conversion circuit operates in a light-load mode. The power conversion efficiency of the power conversion circuit is higher when the output inductor current is within the specified current range than when the output inductor current is outside the specified current range. This solution improves the power conversion efficiency by adjusting the inductor current of the output inductor in the power conversion circuit under light-load mode, keeping the output inductor current within a specified current range.
