- Kurzbeschreibung<p>Power quality and voltage/current harmonics have been matter of concern in most research on power networks since many years ago. This problem is aggravated in harmonic environment caused by power electronic converters. The harmonic components distort the ac current and voltage at the point of common coupling (PCC) and therefore affects the other adjacent loads connected to the same bus. Excessive reactive power demand increases feeder losses and reduces the active power flow capability of distribution system. Moreover, unbalancing affects the operation of transformers and generators. Presence of power filters using semiconductor switches has proved to be a solution to the electric distribution system facing these problems (reactive power, harmonics, and unbalanced loading). One of the equipment which is used to eliminate such harmonics is active power filter (APF) that is employed in many power networks and industries to suppress the current harmonics generated by nonlinear loads like rectifiers. The major issue related to the effective operation of APF is its controllability to compensate reactive power, harmonics, and unbalanced loading.</p>
