Document Type and Number:
WIPO Patent Application WO/2024/032078
Kind Code:
A1
Abstract:
The present application provides a circuit control method and unit, and an apparatus. The method is applied to a power supply apparatus; the power supply apparatus comprises a switch boost circuit; and the switch boost circuit comprises at least one power semiconductor device. The circuit control method comprises: collecting an input signal and an output signal of the switch boost circuit; according to the input signal, the output signal, and circuit information of the switch boost circuit, determining, as a target control solution, a control solution having the highest electric energy conversion efficiency from a plurality of control solutions to be selected, wherein the control solutions to be selected comprise control solutions corresponding to each of a plurality of working modes of the switch boost circuit for the at least one power semiconductor device; and controlling on and off of the at least one power semiconductor device according to the target control solution. According to the present application, the control solution of a power semiconductor device can be adjusted in time, thereby improving the overall electric energy conversion efficiency of the circuit.
