Its an IEEE paper on Harmonic Mitigation in a Virtual Air Gap Variable Reactor via Control Current Modulation

Comparison of Control Algorithms for Shunt Active Filter for Harmonic Mitigation

Mitigation Of Voltage Sag And Current Harmonic Elimination Using Reference Signal Generation Method Based On UPQC. This paper proposes a reference signal generation method for the UPQC adopted to compensate both current and voltage quality problems

Compared to the conventional selective harmonic mitigation-pulse width modulation (SHM-PWM), the selective harmonic mitigation-pulse width and amplitude modulation (SHM-PWAM) control strategy for multilevel inverters has considerable advantages such
