WebFeb 17, 2024 · The reactive power required for compensation is generated by parallel connected shunt capacitance (often in the form of tuned or damped harmonic filters). The order of harmonic filters depends primarily on the harmonic (number) currents generated by the troublesome loads. WebThis paper presents a three-phase, 3-level voltage source inverter based active filter for power line conditioning to improve power quality in the distribution network. The active filter compensates both reactive power and harmonic currents drawn by non-linear loads; additionally it facilitates power factor corrections.
