Detection method of interharmonic pairs-caused voltage peak fluctuation flicker
Energy Reports, 2022 Interharmonics of high frequency will cause voltage’s peak value fluctuation, which will result in flicker of fluorescent lamp and LED lamp. To realize accurate evaluation of the flicker, a method based on multiresolution S-transform is proposed to ...

A review on flicker-free ac-dc LED drivers for single-phase and three-phase ac power grids [PDF]
, 2019 Light-Emitting Diodes (LEDs) are coming strongly into the lighting market due to their advantages over conventional lighting solutions: energy efficient, controllable in both light and color, long lifetime, lack of a warm-up period and high power density.

Flicker of Modern Lighting Technologies Due to Rapid Voltage Changes
Energies, 2019 The purpose of the present paper is to evaluate the sensitivity of modern lighting technologies to different types of RVCs. In order to do that, 27 modern lamps—mainly LED—have been subjected to real RVCs and their response has been assessed.

Superconvergence of Topological Entropy in the Symbolic Dynamics of Substitution Sequences
, 2018 We consider infinite sequences of superstable orbits (cascades) generated by systematic substitutions of letters in the symbolic dynamics of one-dimensional nonlinear systems in the logistic map universality class.

High Resolution Flicker-Noise-Free Frequency Measurements of Weak Microwave Signals
, 2011 Amplification is usually necessary when measuring the frequency instability of microwave signals. In this work, we develop a flicker noise free frequency measurement system based on a common or shared amplifier.

Metrology and 1/f noise: linear regressions and confidence intervals in flicker noise context [PDF]
, 2015 1/f noise is very common but is difficult to handle in a metrological way. After having recalled the main characteristics of stongly correlated noise, this paper will determine relationships giving confidence intervals over the arithmetic mean and the ...
