Abstract
A controller for controlling a voltage converter includes a compensation circuit, an acceleration circuit and a driving circuit. The voltage converter generates a real-time charging current, a real-time battery voltage and a system voltage. The compensation circuit compares the real-time charging current with a preset charging current to generate a first comparison result, compares the real-time battery voltage with a preset battery voltage to generate a second comparison result, compares the system voltage with a preset reference voltage to generate a third comparison result, and generates a compensation voltage based on the first, second and third comparison results. The acceleration circuit adjusts the compensation voltage based on a state of charge of the battery and the system voltage. The driving circuit generates a first switching signal and a second switching signal based on the compensation voltage to control an upper switch and a lower switch of the voltage converter, respectively.
