The reference current generation (RCG) is a crucial part in the control of a shunt active power filter (APF). A variety of RCG techniques have been proposed in literature. Among these, the instantaneous reactive power theory, called pq theory...

Compared with the traditional L filters, the high order LCL and LLCL filters for grid integration of voltage source converters offer better switching harmonic attenuation even with smaller passive elements. However, the ...

This paper proposes a novel adaptive recursive discrete Fourier transform (ARDFT) technique for the reference current generation of single-phase shunt active power filters (APFs). The suggested method is robust to input frequency changes and exactly...

The ever increase of nonlinear loads in electric distribution networks causes many problems due to the high level of harmonic currents. This paper proposes a new technique for controlling a single phase shunt active power filter based on a selective...

This paper proposes the design and implementation of a single-phase shunt active power filter based on the PQ theory to compensate current harmonics in electric distribution networks. The proposed method precisely extracts current harmonics by using...
