Abstract—Active harmonic resistor (AHR) has been

proposed to damp the resonance caused by reactive

compensation capacitors and line inductance in

power system. In this paper, a specific

current-controlled method for AHR is proposed

and modeled firstly, and then the design strategy

for AHR optimal resistor value is studied in detail.

Simulation and laboratory experiment results

proved that using this proposed current control

method the AHR impedance characteristics can

simulate a resistor in a wide band and AHR can

suppress the harmonic amplification significantly
