A Noncontact Voltage Measurement System for Power-Line Voltage Waveforms
(Institute of Electrical and Electronics Engineers, 2019-07)
This paper presents the design and implementation details of a complete noncontact (NC) voltage acquisition system, which allows the measurement of power-line voltage waveforms without galvanic contact. The system is ...
Noncontact AC Voltage Measurements: Error and Noise Analysis
(Institute of Electrical and Electronics Engineers, 2018-08)
A capacitive noncontact ac voltage measurement technique and its feasibility to measure arbitrary waveform signals are analyzed. The method provides self-calibration of the scale factor, an important feature considering ...
Observer-Based Grid-Voltage Sensorless Synchronization and Control of a VSI-LCL Tied to an Unbalanced Grid
(Institute of Electrical and Electronics Engineers, 2019-07)
This paper proposes an observer-based grid-voltage sensorless strategy that allows to implement the synchronization and control of an LCL grid-tied voltage source inverter. By using exclusively the measurement of the current ...
Changes in particle area measurements due to SEM accelerating voltage and magnification
(Wiley-liss, Div John Wiley & Sons Inc, 2003-08)
Scanning electron microscopy (SEM) images of polymer blends followed by digital image analysis is a rapid and easy method for the measurement of particle size and dispersion. The particle size determination is done with ...
Active Current Mirrors for Low-Voltage Analog Circuit Design
(Birkhauser Boston Inc, 2017-12)
In this work, active current mirrors using sensing resistors and a pass transistor in a feedback loop will be examined in detail. First, several non-idealities in this family of circuits, such as offset, noise, output ...
Current-voltage curves of eutectic In-Sb-Te thin films for phase change memory devices
(Emerald, 2019-10)
Purpose: The purpose of this paper is to investigate electrical properties of eutectic In8Sb8Te84 and In10Sb51Te39 as made thin films to evaluate their potential for non-volatile phase-change memories, once the thermal ...
Bioelectrical Circuit from Charged Proteins as Biomarker of Renal Damage
(Institute of Electrical and Electronics EngineersPE, 2021-12-15)
At first phases of renal damage, kidney would allow to pass giant proteins such as albumin whose size is of order of nm., surpassing the glomerular zone and therefore going to the Bowman's space. In this manner at the ...
Output Admittance Synthesizer for Synchronverters
(Institute of Electrical and Electronics Engineers, 2021-05)
This paper proposes an "Output Admittance Synthesizer" (OAS), a feedback block that enables the Synchronverter (SV) to have specific values of output admittance (modulus and phase), at specified harmonic frequencies (and ...
Multiple resonant controllers strategy to achieve fault ride-through and high performance output voltage in UPS applications
(The Institution of Engineering and Technology, 2018-11-13)
A control strategy to achieve fault ride-through capability and to provide high performance of the output voltage of a single-phase uninterruptible power supply (UPS) inverter is proposed in this study. This strategy ...
