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 oscillator are the key...

One of the most important aspects for the proper operation of the single-phase grid-tied power-conditioning systems is the synchronization with the utility grid. Among various synchronization techniques, phase locked loop (PLL)-based algorithms have...

-loop and pre-loop filtering techniques depending on their position in the PLL structure. Inspired from the concept of delayed signal cancellation (DSC), the idea of cascaded DSC (CDSC) has recently been introduced as an effective solution to improve...

is unbalanced and/or distorted. To overcome this challenge, incorporating moving average filter(s) (MAF) into the PLL structure has been proposed in some recent literature. A MAF is a linear-phase finite impulse response filter which can act as an ideal low...

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 ...
