CURRENT AND VOLTAGE ADJUSTMENT METHOD, APPARATUS AND DEVICE, AND STORAGE MEDIUM

WIPO Patent Application WO/2021/036619

A1

A current and voltage adjustment method, apparatus (40) and device (50), and a storage medium. The method comprises: obtaining the constant current value of an input constant current and the constant voltage value of an input constant voltage, and obtaining the rated current value and rated voltage value of a driven body (S101), wherein the rated current value is less than or equal to the constant current value, and the rated voltage value is less than or equal to the constant voltage value; according to a first ratio between the rated current value and the constant current value, generating a first PWM signal with a duty ratio being the first ratio (S102); according to a second ratio between the rated voltage value and the constant voltage value, generating a second PWM signal with a duty ratio being the second ratio (S103); and adjusting the constant current by using the first PWM signal to input the current with the rated current value to the driven body, and adjusting the constant voltage by using the second PWM signal to input the voltage with the rated voltage value to the driven body (S104).
