PI and fuzzy logic controllers for shunt active power filter - A report

► Shunt active power filters proposed for harmonics and reactive power compensation. ► PI or FLC is used to estimate the magnitude of reference current by controlling the DC-side capacitor voltage. ► The shunt APF is implemented with VSI and switching pulses are derived through a novel adaptive-fuzzy-HCC. ► A comparative assessment of fixed-HCC, adaptive-HCC and adaptive-fuzzy-HCC techniques is carried out. ► THD of the source currents is in compliance with IEEE 519 and IEC 61000-3 harmonic standards.
