  • Current compensation module, charging apparatus, and charging apparatus controlling method
    Patent number: 9065288
    Abstract: A current compensation module, a charging apparatus, and a charging apparatus controlling method are disclosed. The current compensation module is used for controlling an outputted charging current in order to charge a battery module. The current compensation module includes a transition unit, a proportional controlling unit, and an integral controlling unit. The transition unit allows an internal signal of the current compensation module increasing from a first voltage. When the internal signal attains to a second voltage, the proportional controlling unit will output a proportional controlling signal to adjust the charging current. When the charging current attains to a rated output current, the integral controlling unit incorporates with the proportional controlling unit to output a proportional-integral controlling signal in order to control and adjust the charging current for the battery module, and to suppress the output overshoot current of the charging apparatus.
