Abstract
A controller for controlling a voltage converter that generates a real-time charging current and a real-time charging voltage, including a compensation circuit, a driving circuit and a control circuit. The compensation circuit compares the real-time charging current with a preset charging current to generate a first comparison result, compares the real-time charging voltage with a preset battery voltage to generate a second comparison result, and generates a compensation voltage. The driving circuit generates a pulse width modulation signal based on the compensation voltage. The control circuit generates a control signal based on the pulse width modulation signal and a current indication signal. The driving circuit further generates a first switching signal based on the pulse width modulation signal to control an upper switch of the voltage converter and generates a second switching signal based on the control signal to control a lower switch of the voltage converter.
