CHARGING CIRCUIT, TERMINAL AND CHARGING METHOD Russian patent published in 2020 - IPC H02J7/02 H02M3/07 G05F1/10 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to the electronic circuits technology. Charge circuit, terminal and charging method are proposed. It is achieved by the fact that charging circuit comprises control circuit and voltage reduction circuit connected to control circuit; wherein the control circuit is configured to obtain a feedback signal indicating the control signal generation frequency, generation of control signal based on feedback signal and transmission of control signal to voltage reduction circuit, and voltage reduction circuit is configured to obtain input voltage and control signal, perform input voltage reduction process based on control signal and supply output voltage to battery, wherein the output current corresponding to the output voltage is greater than the input current corresponding to the input voltage, and the output voltage is configured to determine the generation frequency.

EFFECT: technical result consists in improvement of efficiency of charging of battery using higher output current and reduction of thickness of charging line at low level of input current, as a result of which cost of charging line decreases.
