Document Type and Number:
WIPO Patent Application WO/2023/185086
Kind Code:
A1
Abstract:
The present application relates to a current control circuit, an electric energy provision apparatus, a device, and a current control method and apparatus. A current control circuit 01 comprises: a conversion circuit 10, which is used for converting an input voltage and then outputting the converted input voltage; and a control circuit 20, which is used for controlling, according to a reference voltage and an output voltage of the conversion circuit 10, an output current of the conversion circuit 10 to be a preset current, wherein the reference voltage is determined according to the input voltage, and a waveform of the preset current changes as a waveform of the input voltage changes. By using the current control circuit, a control circuit in the current control circuit can control, according to a reference voltage and an output voltage of a conversion circuit, an output current of the conversion circuit to be a preset current, and since a waveform of the preset current changes as a waveform of an input voltage changes, the output current of the conversion circuit can also change as the input voltage of the conversion circuit changes, such that a final output current of the conversion circuit correspondingly changes as the input voltage changes.
