Influência mútua entre harmônicos e cargas não-lineares

This work presents and analyzes cases where mutual influence between voltage and/or current harmonic content and nonlinear loads occurs. These influences are exemplified by means of undertaken measurements and simulations, such as: the supply of nonlinear loads with different voltage waveforms, especially loads composed of a rectifier with capacitive filter; the influence of current harmonic content in the supply voltage; the combination of three-phase and single phase loads; and the mutual influence of harmonic content of shunt-connected loads, emphasizing, in these last two cases, the possibility of harmonic compensation.
