APPARATUS AND METHOD FOR CONTROLLING ELECTRIC CURRENTS

Disclosed are an apparatus and a method for controlling electric currents. The apparatus for controlling electric currents according to the present invention includes: a pulse width modulation (PWM) signal generating unit configured to generate a PWM signal; a first switch unit connected with the PWM signal generating unit, and configured to receive the PWM signal and generate a switch control signal corresponding to the PWM signal; a second switch unit connected with the first switch unit, and configured to receive the switch control signal and connect or block a flow of a current from a rectifier to a battery according to the switch control signal; and a current decreasing unit connected with the second switch unit, and configured to decrease a current value of a current passing through the second switch unit and provide the battery with a current having the decreased current value.
