Disturbance currents of inverters

This paper presents a research on a DC-AC (AC-AC) inverter used in a locomotive drive. The research is focused on creation of harmonic currents in DC-link. The content of some harmonics is restricted by standards and we call such harmonics as disturbance currents. The goal of this research is to found effects which are adherent to disturbance currents and on the basis of this to implement the changes of the power circuit, the control algorithm and the modulation.
