Detection Algorithm For Active Filters Based On Adaptive Inverse Control
In order to accurately compensate the harmonics and reactive power of the active power filter, a paralleltype active filter detection algorithm based on adaptive inverse control is proposed to control and follow the DC capacitor voltage, obtain the ...
