Calculations of diversified harmonic currents in multiple converter systems

The proliferation of electronic switching into a wide variety of power electronics devices has raised serious concerns over the adequacy of the available harmonic analysis methods in handling the different issues associated with the use of these devices. One of the issues, which still need more investigations, is the determination of the diversified harmonic currents produced by power electronics based loads when harmonic phase angle dispersion is taken into consideration. This paper presents a simple method to calculate an accurate and quick estimation of the diversified harmonic currents especially, in a system with multiple power electronic based loads
