Two types of ictal phase-amplitude couplings in epilepsy patients revealed by spectral harmonicity of intracerebral EEG recordings
(Elsevier Ireland, 2020-08)
Objective: Spectral harmonicity of the ictal activity was analyzed regarding two clinically relevant aspects, (1) as a confounding factor producing ‘spurious’ phase-amplitude couplings (PAC) which may lead to wrong conclusions ...
Neural-network-based approach applied to harmonic component estimation in microgrids
(2021-01-01)
Power quality in smart microgrids must be carefully analyzed, whereas adverse consequences may harm the electrical systems without power management and appropriate measures. The main goal of this paper is to develop a 5th, ...
Two-Sample PLL with Harmonic Filtering Capability Applicable to Single-Phase Grid-Connected Converters
The two-sample phase locked loop (2S PLL) in single-phase digitally controlled grid-connected power converters provide synchronization with a minimal computational burden. However, the distortion of the grid voltage ...
DC and AC side harmonics in CCC converters
(IEEE, 2014)
Bifurcation theory and harmonic content of oscillations
(Unión Matemática Argentina, 2006-12)
The harmonic content of periodic solutions in ODEs is obtained using standard techniques of harmonic balance and the fast Fourier transform (FFT). For the first method, the harmonic content is attained in the vicinity of ...
Impact of supply voltage distortion on the current harmonic emission of non-linear loads
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-07-01)
Electronic devices have a non-linear characteristic and emit harmonics into the low voltage grid. Different harmonic studies analyze their impact on the grids based on different types of harmonic models. The most used model ...
Harmonics filtering and detection of disturbances using wavelets
(1999-12-01)
Traditional mathematical tools, like Fourier Analysis, have proven to be efficient when analyzing steady-state distortions; however, the growing utilization of electronically controlled loads and the generation of a new ...
Distorções harmônicas: estudo de caso de uma planta industrial
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Eletrotécnica, 2014-08-13)
This paper discusses a case study in depth about an electrical phenomenon in facilities known as harmonics, covering the full range of study that involves their behavior, divided into topics that would be needed to further ...
