Abstract

In this paper a new DC line current compensator is presented. The proposed converter is able to compensate very low amplitude current harmonics and is very useful in railway applications where harmonic pollution can produce interference in the signaling systems over DC lines. The active compensator is modular and composed by multiple cells connected in series and controlled in order to minimize the modulation current ripple. Moreover a design criteria are shown and simulation results demonstrate the effectiveness of the proposed solution.
