Title:
METHOD FOR SUPPRESSING OVERSHOOT OF OUTPUT VOLTAGE OR OUTPUT CURRENT, CHARGING DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/024354
Kind Code:
A1
Abstract:
The present application discloses a method for suppressing overshoot of an output voltage or an output current, a charging device, and a medium. The method for suppressing overshoot of the output voltage or the output current comprises: determining a loop in an open-loop state in a closed-loop control circuit; obtaining a wave transmitting control value outputted in the current beat of the closed-loop control circuit; performing value assignment of the wave transmitting control value outputted in the current beat to an open-loop output value of the current beat, wherein the open-loop output value is an output value of the loop in the open-loop state; and calculating the open-loop output value of the next beat of the loop in the open-loop state by using the value-assigned open-loop output value of the current beat. The method for suppressing the overshoot of the output voltage or the output current can reduce a take-over time delay of a voltage loop and a current loop of a battery power supply during switching, and avoid the problem of overshoot of the voltage loop and the current loop during switching.
