Damping apparatus and damping method of converter system

Abstract

The present disclosure relates to a damping apparatus of a converter system, which compensates an input voltage reference being transmitted to a converter to damp an output current of a harmonic filter that is connected between an output end of the converter and a system, including a voltage reference compensation unit configured to compensate for the input voltage reference using a ratio between inductances of inductors included in the harmonic filter; a capacitor voltage value compensation unit configured to compensate for a voltage value of a capacitor included in the harmonic filter using the ratio between the inductances of the inductors; and a voltage reference generation unit configured to generate a final voltage reference by subtracting the compensated voltage value of the capacitor from the compensated input voltage reference.
