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 ...
Fuzzy linguistic model for bioelectrical impedance vector analysis
(CHURCHILL LIVINGSTONEEDINBURGH, 2012-10)
Backgrounds Ea aims: The boundaries between the categories of body composition provided by vectorial analysis of bioimpedance are not well defined. In this paper, fuzzy sets theory was used for modeling such uncertainty. ...
Implementation of output impedance in single-phase inverters with repetitive control and droop control
(Institution of Engineering and Technology, 2020-11)
A strategy for the implementation of the output impedance in single-phase inverters connected in parallel with droop control for uninterruptible power supply applications is proposed in this study. The proposal allows the ...
A new microcontrolled structural health monitoring system based on the electromechanical impedance principle
(2013-01-01)
This article presents a new method to detect damage in structures based on the electromechanical impedance principle. The system follows the variations in the output voltage of piezoelectric transducers and does not compute ...

Estudo da estabilidade de um conversor buck com filtro de entrada considerando a análise de impedâncias
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2018-12-13)
A switching converter which has effective output voltage control operates as a constant
power load and behaves as a negative impedance. When an input filter is connected
to the converter to smooth the absorbed current ...
roop-controlled inverters small-signal impedance characterization for stability studies
(Universidad de Chile, 2019)
Microgrids are one of the key technologies to facilitate the integration of large amounts of renewable generation technologies to the main grid. The main power supplies inside the microgrid are power electronic devices ...
A high input impedance single-ended input to balanced differential output amplifier
(Institute of Electrical and Electronics Engineers, 2019-05)
A high input impedance circuit to convert a single-ended (SE) voltage to its differential counterpart is proposed. It allows setting the common-mode (CM) output voltage to a reference voltage vR, while providing gain and ...
