Effect of Rectangular Voltage Fluctuations on Currents of Single-Phase Induction Motors

open access: yesScientific Journal of Gdynia Maritime University
Various power quality disturbances commonly occur in a power system, including voltage fluctuations. These can be analysed as simultaneous occurrences of voltage subharmonics and interharmonics of various frequencies – components of frequency less than ...

Induction motors subject to regular voltage fluctuations: Stator and rotor current analysis from a heating perspective [PDF]

open access: yes, 2012
Induction motors are widely applied in industry. Their performance strongly depends on relative power supply quality, such as voltage sags, harmonics, voltage unbalance and voltage fluctuations.

Coordinated Control of Second-Order Harmonic Voltage and Current Fluctuations in Cascaded H-Bridge Inverter with Supercapacitor and DC-DC Stage at Variable Output Frequencies

open access: yesCES Transactions on Electrical Machines and Systems
In the cascaded H-bridge inverter (CHBI) with supercapacitor and dc-dc stage, inherent second-order harmonic power flows through each submodule (SM), causing fluctuations in both the dc-link voltage and the dc-dc current.

Four-terminal voltage fluctuations in disordered graphene nanoribbons: Anderson and anomalous localization effects [PDF]

open access: yes
Voltage is a sensitive quantity to quantum interference in coherent electronic transport. We study the voltage fluctuations in disordered graphene nanoribbons with zigzag and armchair edge terminations in a four-terminal configuration.

Simultaneous Planning of PV and DSTATCOM for Combined Mitigation of Voltage Deviation and Unbalance [PDF]

open access: yes
The increased integration of photovoltaic systems (PVs) and unbalanced loads in low-voltage (LV) distribution systems has negative consequences on the overall performance of the utility grid (UG), resulting in voltage imbalance, power losses, line ...

Mechanism behind the occurrence of noise peaks in components with nonlinear voltage-current characteristics

open access: yesТехнологія та конструювання в електронній апаратурі, 2004
It is shown that the previously established mechanism for converting the current spectrum of conductivity fluctuations Sg(f) into voltage fluctuations Su(f) in a sample with a nonlinear voltage-current characteristic Su(f) = Sg(f)rdU (where rd is the ...
