To improve the performance of phase-locked loops (PLLs) under adverse grid conditions incorporating different filtering techniques into their structures have been proposed in literature. These filtering techniques can be ...

The phase locked-loops (PLLs) are probably the most widely used synchronization technique in grid-connected applications. The main challenge associated with the PLLs is how to precisely and fast estimate the phase and ...

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 ...

A phase-clocked loop (PLL) is a closed-loop feedback control system which synchronizes its output signal in frequency as well as in phase with an input signal. The phase detector, the loop filter, and the voltage controlled ...

Recently, several advanced phase-locked loop (PLL) techniques have been proposed for single-phase applications. Among these, the Park-PLL and the second-order-generalized-integrator-based PLL are very attractive, owing to their simple digital...

In grid-connected applications, the synchronous reference frame phase-locked loop (SRF-PLL) is a commonly used synchronization technique due to the advantages it offers such as ease of implementation and robust performance. ...
