Evaluating harmonic and intermodulation distortion of mixed signals processed with dynamic range compression [PDF]

open access: yes, 2014
Dynamic range compression of simple signals results in harmonic nonlinear distortion. However, for summed signals, predominantly inharmonic intermodulation distortion (IMD) is generated.

Hidden Harmonic Asymmetry in a Balanced Three-Phase Building: Evidence from Field Measurements

open access: yesApplied Sciences
The increasing penetration of power electronic devices and distributed generation is significantly altering power quality conditions in low-voltage systems. While power quality assessment is commonly based on RMS currents, voltage quality indicators, and

Harmonic distortion in microwave photonic filters

open access: yesOptics Express, 2012
We present a theoretical and experimental analysis of nonlinear microwave photonic filters. Far from the conventional condition of low modulation index commonly used to neglect high-order terms, we have analyzed the harmonic distortion involved in microwave photonic structures with periodic and non-periodic frequency responses.

Annealing effects on single-phase E-I transformer performance under nonlinear loads

open access: yesJurnal Eltek
Single-phase E-I transformers are widely used in power-conversion applications, including grid-connected flyback micro-inverters for solar photovoltaic systems, yet their performance often deteriorates due to high core loss and harmonic distortion ...
