This work presents a phase-locked loop (PLL) algorithm for the detection of positive-sequence and negative-sequence grid voltages in three-phase systems. Since it employs an adaptive filter (AF), it is possible
A phase-locked loop (PLL) is a closed-loop feedback control system that generates and outputs a signal in relation to the frequency and phase of an input ("reference") signal. A phase-locked loop circuit responds to both the frequency and the phase of the input signals, automatically raisi...
Doing so computes the resistance and capacitance values to meet the soft design goal based on the target loop shape. Run the tuning algorithm with five different initial value sets in addition to the initial values defined during the creation of the tunable scalar real parameters. Get Options ...

In parallel, a certain algorithm known as a lock detector is run which generates a binary output depending on whether the PLL has acquired lock or not. Since the loop constants are reconfigurable in this scenario, their values are changed such that the PLL bandwidth BnBn is reduced to a ...
Three-phase phase-locked loop algorithm and application to a static synchronous compensator 2021, Electric Power Systems Research Citation Excerpt : Otherwise, if |Vcomp|<|Vg|, the compensator is responsible for absorbing reactive power. Even though this FACTS device was formerly proposed for the con...
In addition, the proposed DCDL is adopted in phase locked loop. Keywords: digitally controlled delay lines (DCDL), glitches, NIKOLIC sense amplifier based flip-flop, dual edge triggered sense amplifier based flip-flop, phase locked loop (PLL). 1. INTRODUCTION Glitching is the most common ...
A phase-locked loop (PLL) and voltage controlled oscillator (VCO) outputs an RF signal at a certain frequency, and ideally this signal would be the only signal present at the output. In reality, there are unwanted spurious signals and phase noise at the output. This article discusses the si...
A neuronal phase-locked loop (NPLL) that can decode temporally-encoded information and convert it to a rate code is based on an algorithm similar to that of the electronic PLL, but is a stochastic device, implemented by neural networks (real or simulated). The simplest embodiment of the NP...
