Abstract:
Due to the discoloration properties under different applied voltages, dye-doped polymer-dispersed liquid crystal (PDLC) films are widely used as camouflage nets and invisibility cloaks. However, the range of the discoloration has an intuitive effect on their applications. In this work, we studied the gamut range of PDLC film doped with dyes of red, green, blue, and yellow, with the concentration corresponding to the minimum haze of these dyes. The influence of the applied voltage on the color range of single-layer and double-layer films with different backgrounds was studied. The relationship of the voltage with the color was set from 0 V to 60 V at steps of 5 V, to characterize the discoloration of the PDLC films. The results showed that the films could cover 42.48% of the sRGB gamut and even exceed the range.

Abstract:
A novel unidirectional hybrid PFC rectifier topology based on SEPIC and boost converters is proposed, which is applicable to various industrial applications such as electric vehicle charging stations, variable speed AC drives, and energy storage systems. Compared to other rectifiers, the proposed SEPIC-boost-based rectifier exhibits continuous current on the AC side, lower voltage stress on the active switches, a wider range of DC output voltage, no auxiliary DC-DC converters, and a high step-up static voltage gain operating with low input voltage and a low step-up static gain for the high-input-voltage operation. These traits allow the SEPIC-boost-based rectifier to utilize smaller input-side harmonic filtering inductors and adopt active switches with lower voltage ratings, resulting in reduced conduction losses. Additionally, the proposed rectifier features power factor correction and high boost/buck voltage-gain capabilities, simplifying control for electric vehicle charging and expanding its range of applications. In this paper, the operating principle of the novel topology is presented first, and then the mathematical model of the proposed rectifier is built. Based on this, the comparison between the proposed topology and conventional boost and SEPIC converters is given. Furthermore, the control strategy, including the high-power-factor control and the balancing control to the DC capacitor voltages, is discussed. Finally, to validate the accuracy of the proposed rectifier’s theoretical research, a 500-W SEPIC-boost rectifier system has been constructed in the laboratory, generating a 200/120 Vdc output voltage from a 155 Vpk/50 Hz power source.

Abstract:
A newly developed conical anode field emission electron gun (FE-GUN)has been installed on the JSM-840F Scanning Electron Microscope (SEM). The cross sectional view of the column is shown in Fig. 1. The gun is usable at a wide accelerating voltage range from 0.5 kV to 40 kV, and is suitable for general purpose SEMs. The gun can be used within the virtual source range even at an extract voltage as high as 7 kV and an accelerating voltage as low as 0.5 kV. The extract voltage can be raised up to 7 kV even when the emitter tip radius becomes larger after repeated flashing for smoothing the emitter tip surface. This allows elongation of the emitter life.With the FE-GUN, since the electron source (virtual source) moves with accelerating voltage change, an image may disappear due to the deviation of the electron probe from the optical axis when the accelerating voltage is changed.

Abstract:
This paper proposes a novel three-phase voltage source inverter dead-time compensation strategy for accurate compensation in wide current regions of the inverter. In particular, an analysis of the output voltage distortion of the inverter, which appears as parasitic components of the switches, was conducted for proper voltage compensation in the low current region, and an on-line compensation voltage controller was proposed. Additionally, a new trapezoidal compensation voltage implementation method using the current phase was proposed to simplify realizing the trapezoidal shape of the three-phase compensation voltages. Finally, when the proposed dead-time compensation strategy was applied, the maximum phase voltage magnitude in the linear modulation voltage regions was defined to achieve smooth operation even at high modulation index. Simulations and experiments were conducted to verify the performance of the proposed dead-time compensation scheme.

Abstract:
The solar energy conversion driven by the solar sensor (or the so-called solar cell) has become an important and feasible way to solve global energy crisis while at the same time minimizing environmental pollution. The solar charge controller is the key of its active system for the signal processing circuits involved. In this paper, a fully integrated solar charge controller is presented. The charger has wide input voltage range about 10–28 V for the solar-powered panel. The input loop regulation is used here as the maximum power point tracking protection. This charger also provides different kinds of battery voltages about 4–12 V. The controller system uses just one error amplifier (EA) and no external compensation components is needed. Besides, this controller has 600-kHz pulse-width modulation (PWM) and offers the over-current/over-voltage protection. Other components like bandgap, reference generator, saw-tooth generator, register controller and driver circuits are all implemented in this circuit. This chip is fabricated in a 0.4-μm 5 V/40 V 2P4M process. The power consumption of this full-integrated solar charge controller IC is about 10 mA.

Abstract To optimize the online voltage monitoring technology of the power grid and realize real-time fault warning for the power grid and capacitive devices such as current transformers (CT), this paper proposes a wide-frequency range voltage monitoring method based on current transformers according to the idea of measuring the leakage current of capacitive devices to restore the line voltage. The method measures the current transformer leakage current to invert the bus voltage and uses a wide frequency range current sensor to meet the measurement of high-frequency waveforms. This paper designs a CT wide-frequency range voltage monitoring device based on this method and conducts field tests of the device’s measurement effects. Through the fault monitoring test and voltage monitoring test, it is verified that the monitoring device is fully functional and can achieve accurate monitoring of harmonics, end shield current, relative dielectric loss, high-frequency partial discharge, and bus-voltage with high amplitude and high frequency, which can provide support for fault analysis and insulation design improvement and is of great significance to ensure safe and stable operation of the power grid.

Abstract:
A new hybrid inductor-inductor-capacitor (LLC) converter is investigated to have wide voltage input operation capability and zero-voltage turn-on characteristics. The presented circuit topology can be applied for consumer power units without power factor correction or with long hold-up time requirement, photovoltaic energy conversion and renewable energy power transfer. To overcome the weakness of narrow voltage gain of resonant converter, the hybrid LLC converter with different turns ratio of transformer is presented and the experimental investigation is provided to achieve wide voltage input capability (400 V–50 V). On the input-side, the converter can operate as full bridge resonant circuit or half bridge resonant circuit with input split capacitors for high or low voltage input region. On the output-side, the less or more winding turns is selected to overcome wide voltage input operation. According to the circuit structures and transformer turns ratio, the single stage LLC converter with wide voltage input operation capability (400 V–50 V) is accomplished. The laboratory prototype has been developed and the experimental waveforms are measured and demonstrated to investigate the effectiveness of the presented hybrid LLC converter.

Abstract:
The conventional power factor correction circuit has a fixed output voltage. However, in some applications, a PFC circuit with a wide output voltage range is needed. A single phase power factor correction circuit with wide output voltage range is developed in this work. After a comparison of two main power stage candidates (Buck+Boost and Sepic) in terms of efficiency, complexity, cost and device rating, the buck+boost converter is employed as the variable output PFC power stage. From the loss analysis, this topology has a high efficiency from light load to heavy load. The control system of the variable output PFC circuit is analyzed and designed. Charge average current sensing scheme has been adopted to sense the input current. The problem of high input harmonic currents at low output voltage is discussed. It is found that the current loop gain and cross over frequency will change greatly when the output voltage changes. To solve this problem, an automatic gain control scheme is proposed and a detailed circuit is designed and added to the current loop. A modified input current sensing scheme is presented to overcome the problem of an insufficient phase margin of the PFC circuit near the maximum output voltage. The charge average current sensing circuit will be bypassed automatically by a logical circuit when the output voltage is higher than the peak line voltage. Instead, a resistor is used to sense the input current at that condition. Therefore, the phase delay caused by the charge average current sensing circuit is avoided. The design and analysis are based on a novel air conditioner motor system application. Some detailed design issues are discussed. The experimental results show that the variable output PFC circuit has good performance in the wide output voltage range, under both the Boost mode when the output voltage is high and the Buck+Boost mode when the output voltage is low.<br>Master of Science

Abstract:
DC power systems have a constant DC-link voltage, as well as the advantages such as high stability, high efficiency, small size and light weight; therefore, they are widely used in stand-alone power systems, e.g. the power systems in aircrafts and automobiles, isolated wind power generation systems, etc. Permanent-Magnet Synchronous Generators (PMSGs) possess the advantages including high power density, high efficiency, and high control precision, and have obtained great attention and have been widely used in military, inductry, and daily life. Pulse Width Modulation (PWM) rectifier has been one of the main power conversion topologies thanks to its full controllability. The key point in the dissertation is to study the DC power system consisting of a PMSG to be the main power input device and a PWM rectifier to be the main power conversion topology. The objective of control is to output a constant DC-link voltage in a wide PMSG speed range. Since the PM-excited flux linkage is constant, when the PMSG is working at a high speed, field-weakening is needed to stabilize the stator voltage, further to stabilize the DC-link voltage. Hybrid excitation may be used to realize the field-weakening, but it has complex structure; no auxiliary devices are needed in the field regulation with the armature current, and can be easily realized with the PWM recifier and field-regulation control strategies. In this dissertation, the typical applications of the DC power systems are first introduced, with a comprehensive analysis and elaboration on the relevant research throughout the world. The research work is focused on the DC power system and its stabilization control, which is composed of a PMSG and a PWM rectifier. The involved research content in this dissertation includes the following aspects: 1. DC power system design with a wide-speed-range PMSGAs for the common DC power systems, PMSG with high power density, high efficiency is selected to the system power input device, usually with a variable-speed prime mover. The PWM rectifier with fully controlled switches is chosen to be the power conversion topology, which converts the AC power generated by PMSG into DC power, and supplies the DC load after the DC filter. The matching between the system requirements and the generator parameters are determined. Through finite-element analysis (FEA), a PMSG with strong field-weakening ability and suitable for wide-speed-range operation has been designed and manufactured, and the system test bench has been built based on dSPACE. 2. Study, analysis, optimization and experimental verification of the traditional control strategiesAccording to the PMSG designed in part 1, the DC-link model has been built, as well as the control model of the traditional control strategies, e.g. field-oriented control (FOC), direct torque control (DTC), and the effectiveness of the DC-link voltage stabilization control has been verified in a wide speed range. The theory of active damping has been proposed and analyzed, and has been utilized in the DC-link voltage control. When the load on the DC-link changes, the dynamic response of the DC-link voltage has been greatly accelerated, and it recovers quickly to its reference value. In the meantime, the performance influence of the prime mover speed on the actual system test bench should be considered. Finally, the performance of FOC and DTC has been compared and analyzed. 3. Analysis and experimental verification of the direct voltage control (DVC), and the comparative study of all the studied control strategiesThe derivation process of DVC has been theoretically analyzed: the inner current loops in FOC have been eliminated to obtain the direct voltage field-oriented control (DVFOC); the reference value of d-axis voltage in DVFOC has been replaced by the product of the stator voltage calculated by the speed and the load condition, and the sine value of load angle generated by the DC-link voltage PI controller, in order to form the DVC-1. Further, the DC-link voltage PI controller directly outputs the reference value of load angle and it becomes DVC-2. Finally, the comparative study has been carried out among all the studied control strategies.<br>Doctorat en Sciences de l'ingénieur et technologie<br>info:eu-repo/semantics/nonPublished

Abstract:
Abstract The aim of this work was to develop time-to-digital converters(TDC) with a wide measurement range of several hundred microseconds and with a measurement precision of a few picoseconds. Because of these requirements, the focus of this work was mainly on TDC architectures based on the Nutt interpolation method, which has several advantages when a long measurement range is a requirement. Compared to conventional data converters the characteristics of a Nutt TDC differ significantly when, for example, quantization errors and linearity errors are considered. In this thesis, the operating principle of a Nutt TDC is analysed and, in particular, the effects of reference clock instabilities are studied giving new insight how the different phase noise processes can be reliably translated into time interval jitter, and how these affect the measurement precision when very long time intervals are measured. Furthermore, these analytical results are confirmed by measurements conducted with a long-range TDC designed as part of this work. Two long-range TDCs have been designed, each based on different interpolator architectures. The first TDC utilises discrete component time-to-voltage converters(TVC) as interpolators. Other key functionality is implemented on an FPGA. The interpolators use Miller integrators to improve the linearity and the single-shot precision of the converter. The TDC has a nominal measurement range of 84ms and it achieves a single-shot precision of 2ps for time intervals shorter than 2ms, after which the precision starts to deteriorate due to the phase noise of the reference clock. In addition to the discrete TDC, an integrated long-range CMOS TDC has been designed with 0.35μm technology. Instead of TVCs, this TDC features cyclic/algorithmic interpolators, which are based on switched-frequency ring oscillators(SRO). The frequency switching is used as a mechanism to amplify quantization error, a key functionality required by any cyclic or a pipeline converter. The interpolators are combined with a 16-bit main counter giving a total range of 327μs. The RMS single-shot precision of the TDC is 4.2ps without any nonlinearity compensation. Furthermore, a calibration functionality implemented partially on-chip ensures that the accuracy of the TDC varies only ±2.5ps in a temperature range of -30C to 70C. Although implemented with fairly old technology, the interpolators’ effective linear range and precision represent state-of-the-art performance<br>Tiivistelmä Tämän työn tavoitteena oli kehittää aika-digitaalimuuntia (TDC), joilla on laaja satojen mikrosekuntien mittausalue ja muutaman pikosekunnin kertamittaustarkkuus. Näistä vaatimuksista johtuen tässä työssä keskitytään pääasiassa Nuttin interpolointimenetelmään perustuviin TDC-arkkitehtuureihin. Verrattuna tavanomaisiin datamuuntimiin, Nutt TDC:n toiminta poikkeaa merkittävästi, kun tarkastellaan kvantisointi- ja lineaarisuusvirhettä. Tässä väitöskirjatyössä Nuttin menetelmään perustavan TDC:n toiminta analysoidaan, jonka yhteydessä tutkitaan erityisesti referenssioskillaattorin epästabiilisuuksien vaikutusta mittausepävarmuuteen. Tämän pohjalta vaihekohinan eri kohinaprosessit voidaan luotettavasti muuntaa taajuustason kohinatiheysmittauksista aika-tasossa kuvattavaksi aikavälijitteriksi. Nämä teoreettiset tulokset ovat varmistettu yhdellä osana tätä työtä suunnitellulla pitkän kantaman TDC:llä. Teoreettisen tarkastelun lisäksi kaksi pitkän kantaman TDC:tä on suunniteltu, toteutettu ja testattu. Ensimmäinen näistä perustuu erilliskomponenteilla toteutettuun aika-jännitemuunnokseen (TVC) pohjautuvaan interpolointimenetelmään. Analogisten interpolaattoreiden ohella muu olennainen toiminnallisuus toteutettiin FPGA:lle. Interpolaattorit käyttävät Miller-integraattoreita lineaarisuuden ja kertamittaustarkkuuden parantamiseksi. TDC:n nimellinen mittausalue on 84ms ja sillä saavutetaan 2ps:n kertamittaustarkkuus, kun mitattava aikaväli on lyhyempi kuin 2ms, minkä jälkeen mittaustarkkuus heikkenee referenssioskillaattorin vaihekohinan vaikutuksesta. Toinen pitkän kantaman TDC perustuu 0.35μm:n CMOS teknologialla totetutettuun integroituun piiriin. Aika-jännitemuunnoksen sijasta tämä TDC perustuu sykliseen/algoritmiseen interpolointitekniikkaan, jossa taajuusmoduloitua rengasoskillaattoria(SRO) käytetään kvantisointivirheen vahvistamiseksi. Interpolaattorit ovat yhdistetty 16-bittiseen referenssioskillaattorin laskuriin, jolloin TDC:n mittausalue on noin 327μs. Tämän TDC:n RMS kertamittaustarkkuus on 4.2ps, joka saavutetaan ilman epälineaarisuuden kompensointia. Samalle piirille on lisäksi toteutettu kalibrointitoiminnallisuus, jolla varmistetaan TDC:n hyvä mittaustarkkuus kaikissa olosuhteissa. Mittaustarkkuus poikkeaa maksimissaan vain ±2.5ps, kun lämpötila on välillä -30C-70C. Vaikka TDC on toteutettu kohtalaisen vanhalla CMOS teknologialla, interpolaattoreiden efektiivinen lineaarinen alue ja mittaustarkkuus edustavat alansa huippua

Abstract:
This article describes quasi-ballistic electron transport in atomic wires. It begins with a review of experiments on the conduction properties for single metal atoms. Nearly all the information on the properties of such nanocontacts should be extracted from the current and voltage only. Nevertheless, a wide range of techniques has been developed to obtain detailed information. The article proceeds by considering various experimental techniques for characterizing single-atom contacts, along with their application for the study of conducting chains of individual metal atoms and for metal–molecule–metal junctions. Using metallic point contacts and molecular junctions that are of atomic size, it demonstrates that the transport of electrons can be quasi-ballistic and the deviations from perfect transmission can be quantified and interpreted.

Abstract:
This handbook is aimed at helping users of PMTs who are faced with the challenge of designing sensitive light detectors for scientific and industrial purposes. The raison d’être for photomultipliers (PMTs) stems from four intrinsic attributes: large detection area, high, and noiseless gain, and wide bandwidth. Detection involves a conversion process from photons to photoelectrons at the photocathode. Photoelectrons are subsequently collected and increased in number by the action of an incorporated electron multiplier. Photon detection, charge multiplication, and many PMT applications are statistical in nature. For this reason appropriate statistical treatments are provided and derived from first principles. PMTs are characterized by a range of photocathodes offering detection over UV to infra-red wavelengths, the sensitivities of which can be calibrated by National Laboratories. The optical interface between light sources and PMTs, particularly for diffuse or uncollimated light, is sparsely covered in the scientific literature. The theory of light guides, Winston cones, and other light concentrators points to means for optimizing light collection subject to the constraints of Liouville’s theorem (étandue). Certain PMTs can detect single photons but are restricted by the limitations of unwanted background ranging in magnitude from a fraction of a photoelectron equivalent to hundreds of photoelectrons. These sources, together with their correlated nature, are examined in detail. Photomultiplier biasing requires a voltage divider comprising a series of resistors or active components, such as FETs. Correct biasing provides the key to linear operation and so considerable attention is given to the treatment of this topic. Electronic circuits and modules that perform the functions of charge to voltage conversion, pulse shaping, and impedance matching are analysed in detail.

Anatomy of Liberty in Don Quijote de la Manchapresents five major facets of liberty as they appear in the first modern novel. Analyzing the novelist’s attitudes towards religion, feminism, slavery, politics, and economics, Graf argues that Cervantes should be considered a major precursor to great liberal thinkers like Locke, Smith, Mill, Montesquieu, Voltaire, Jefferson, Madison, and Twain. Graf indicates not only the medieval and early modern grounds for Cervantes’s ideas but also the ways in which he anticipated and influenced a wide range of modern articulations of personal freedom. Resistance to tyranny, freedom of conscience, the liberation of women, the abolition of slavery, and the principles of a free market economy are all still fundamental to modern Western Civilization, making Don Quiijote de la Mancha extremely relevant to today’s world. Anatomy of Liberty walks us through how Cervantes’s seminal work both foreshadowed and relates to today’s modern society.
