This paper presents a discussion of the compensation of non-periodic currents such as those associated with arc furnaces. Based on the compensation objectives for different types of load waveforms, the energy storage requirements of the compensator are also presented. Further, basic concepts required in the definition of non active current are presented and illustrated by simulations for a variety of different compensation characteristics of non-periodic currents.
