Abstract

The concept of orthogonal decomposition of the current in a nonlinear single-phase circuit, with a sinusoidal voltage source, into active, scattered, reactive, and generated components is extended to three-phase asymmetrical circuits. It is shown that the source current in such a circuit can be decomposed into five orthogonal components that depend on distinctively different phenomena. Four of them have the same meaning as in the single-phase circuit, with only a change in their mathematical characterization. An additional orthogonal component appears in the source current, because of the load asymmetry
