چکیده
Harmonic problems are not new to electric utility and industrial power systems. In the past, most harmonicrelated problems were caused by large nonlinear loads such as arc furnaces. These types of problems have been effectively mitigated. However, due to the widespread proliferation of power electronic controlled devices nowadays, the problems caused by harmonics are of increasing importance. Power electronic loads offer a number of advantages in controlling power flow and in efficiency, but they perform this by chopping, flatting, or shaping sinusoidal voltages and currents. Harmonics are produced in the process.
