Harmonic sources, flowing from load, why?

[QUOTE="OliskaP, post: 5618445, member: 597405"] Thanks for the explanations [USER=455902]@anorlunda[/USER] and [USER=311008]@Windadct[/USER] , but I am still abit confused when a passive shunt filter is connected in parallel, see figure. So if a nonlinear load causes flow of fundamental + harmonics, but the filter is implemented in such a way that the source only has to supply fundamental. This is confusing to me, unless we can think of: 1. The nonlinear load to "inject" harmonics back into the grid, and the filter is present to absorb it, so that the supply only have to provide fundamental current. [B]OR[/B] 2. The filter providing the harmonic currents to the load, thus again the supply only has to supply fundamental current.[ATTACH=full]108802[/ATTACH] [/QUOTE]
