© 2021 IEEE.This paper proposes a quasi open-loop grid-synchronization technique-based control scheme for active power filter. The proposed filtering technique does not require any direct frequency feedback which has the advantage of unconditional stability. Based on the reference a current, a proportional integral and hysteresis band current control scheme is developed for fast and accurate tracking of the reference current by the APF's converter. Matlab/Simulink-based extensive numerical simulation studies are performed to demonstrate the robust performance of the proposed technique in distorted grid.
