Harmonics in Power Systems and Filter Applications
Black Sea Journal of Engineering and Science, 2019 With the advancing technology, loads in the system have been varied. These loads are always asked to be linear. However, with the effect of progressive semiconductor technology, an increase in nonlinear loads has been observed in the system. Nonlinear loads are loads whose current and voltage characteristics are nonlinear.
