Reducing Conducted Emissions at the Output of Full-Bridge DCDC Converters with High Voltage Steps
(MDPI, 2021-06)
In this work, we analyze the impact of output filter design techniques aimed to reduce conducted emissions at the output of a DCDC power converter. A thorough analysis, based on high-frequency circuit models of the ...

Improving Performance of Compact EMI Filters by using Metallic and Ferrite Sheets
(Institute of Electrical and Electronics Engineers Inc., 2021-08)
Magnetic coupling between components in compact electromagnetic interference filters is one of the main effects that undermine their ability to reduce conducted emissions of power converters at frequencies above several ...

Phase diagram of the two-fluid Lipkin model: A "butterfly" catastrophe
(American Physical Society, 2016-03-31)
Background: In the past few decades quantum phase transitions have been of great interest in nuclear physics. In this context, two-fluid algebraic models are ideal systems to study how the concept of quantum phase transition ...

Simple Setup for Measuring the Response to Differential Mode Noise of Common Mode Chokes
(MDPI, 2020-02)
This work presents a technique to measure the attenuation of differential mode noise provided by common mode chokes. The proposed setup is a simpler alternative to the balanced setup commonly employed to that end, and ...

Use of Mutual Coupling to Decrease Parasitic Inductance of Shunt Capacitor Filters
(IEEE-Institute of Electrical and Electronics Engineers, 2015-12)
In this paper, we propose and study several new designs of a shunt capacitor filter with two surface-mount technology capacitors. These designs make use of mutual inductance effects to increase the attenuation provided by ...

Characterization of Common Mode Chokes at High Frequencies with Simple Measurements
(IEEE, 2018-05)
In this paper, we present a technique to characterize common mode chokes at high frequencies that only requires a measurement, which can be performed with a spectrum analyzer with the tracking generator. This technique is ...

Self-consistent modeling of laminar electrohydrodynamic plumes from ultrasharp needles in cyclohexane
(AIP Publishing, 2017)
This paper presents a self-consistent model of electrohydrodynamic (EHD) laminar plumes produced by electron injection from ultra-sharp needle tips in cyclohexane. Since the density of electrons injected into the liquid ...

Electroconvection in a dielectric liquid between two concentric half-cylinders with rigid walls: Linear and nonlinear analysis
(American Physical Society, 2018)
We study the linear stability and nonlinear behavior of the electroconvection between two concentric halfcylinders with no-slip conditions on all boundaries. The no-slip condition makes impossible to apply the standard modal ...

From thermal to excited-state quantum phase transition: The Dicke model
(American Physical Society, 2017-07)
We study the thermodynamics of the full version of the Dicke model, including all the possible values of the total angular momentum j, with both microcanonical and canonical ensembles. We focus on both the excited-state ...

Excited-state quantum phase transitions in a two-fluid Lipkin model
(American Physical Society, 2017-05-30)
Background: Composed systems have become of great interest in the framework of ground-state quantum phase transitions (QPTs) and many of their properties have been studied in detail. However, in these systems, the study ...
