Power Electronics Converters Applications And Design

The field of cantilever-based sensing emerged in the mid-1990s and is today a well-known technology for label-free sensing which holds promise as a technique for cheap, portable, sensitive and highly parallel analysis systems. The research in sensor realization as well as sensor applications has increased significantly over the past 10 years. In this review we will present the basic modes of operation in cantilever-like micromechanical sensors and discuss optical and electrical means for signal transduction. The fundamental processes for realizing miniaturized cantilevers are described with focus on silicon- and polymer-based technologies. Examples of recent sensor applications are given covering such diverse fields as drug discovery, food diagnostics, material characterizations and explosives detection.

Crop–weed Discrimination by Line Imaging Spectroscopy

The design, construction and evaluation of a contactless battery charger for electric vehicles (EVs) based on inductive power transfer (IPT) is presented in this study. The design of such systems entails a high degree of complexity because of the large number of design parameters involved and, consequently, trade-offs in selecting the key design parameters have to be established. The design process and selection of the IPT system parameters is detailed in this study, considering the most common specifications of EV chargers and the practical issues of the implementation. Regarding the compensation scheme, which is one of the main issues in the design, series compensation in both the primary and secondary has been adopted because of the advantages identified after a comprehensive analysis. A laboratory prototype has been built and tested, providing extensive results of the system performance in terms of efficiency and power transfer capability, considering load power variations, as well as changes in the air gap between coils. A detailed analysis of the efficiency of each stage in the IPT system and their contribution to the overall efficiency is also provided.

Design, implementation issues and performance of an inductive power transfer system for electric vehicle chargers with series–series compensation

Real time monitoring of the physical properties of liquids is of great concern in the automotive industry. For example, tracking the viscosity of lubricating oils is of great importance because they are exposed to dilution with diesel fuel as result of late-injection processes, which are essential for regenerating diesel particulate filters. Here we describe two in-plane movement based resonators and their capability to assess oil dilution with diesel and biodiesel fuels. One of the resonators is a state-of-the-art micron-sized AlN-based rectangular plate, actuated in the first extensional mode in the MHz range. The second resonator is a commercially available millimeter-sized quartz tuning fork, working at 32.7 kHz. Electrical impedance measurements were performed to characterize the performance of both resonators in various liquid media over a wide range of viscosities. These measurements were compared with the results obtained with low-cost electronic circuits also developed in this work. In order to track density and viscosity of different fluids we have measured two parameters by various techniques: the resonance frequency and the quality factor.

Application of quartz tuning forks and extensional microresonators for viscosity and density measurements in oil/fuel mixtures

This paper gives a precise insight into the frequency response of self-actuating cantilevers, extended to high-order modes An original approach is presented, based on a mixed experimental scheme regarding both impedance and laser Doppler interferometry measurements, performed with an impedance analyser and a vibrometer, respectively, and supported by some computational analysis as well The experimental results obtained by the two different techniques agree reasonably well, as for the location of the resonances in the spectrum is concerned However, certain particular modes, torsionally shaped and detected by the vibrometer, show no impedance change due to symmetry reasons A computational model has been successfully employed and utilized to shed some light on this phenomenon The model demonstrates that the induced reaction charge redistribution cancels out only for those particular torsional modes featuring an anti-symmetrical nature; as a consequence, no impedance change is to be expected in the resonances This explanation perfectly fits the impedance measurements carried out, including the missing torsional modesCorrections were made to this article on 10 April 2007 The greyscale figures were replaced with colour versions

Laser vibrometry and impedance characterization of piezoelectric microcantilevers

The response of commercial piezoelectric AFM probes for potential applications in the field of chemical or biological sensors operating in liquids is investigated using laser Doppler vibrometry. The present work investigates the roles played in the frequency response by the density and the viscosity of different water–glycerol mixtures, in a frequency range of up to 1 MHz in air. Since the width of the tested probes is relatively large (and hence the aspect ratio remains small), inertial loading effects dominate viscous effects, unlike in cantilevers characterized by larger aspect ratios. Measurements are compared with results provided by a simplified computer model of a probe immersed in an inviscid surrounding fluid.

Dynamic response of low aspect ratio piezoelectric microcantilevers actuated in different liquid environments

The fermentation process that gradually turns must into wine influences to a large extent the characteristics of the final product The quality of wines would largely benefit from exhaustive testing procedures during the whole fermentation This work demonstrates the potential of refractive techniques to successfully record the fermentation kinetics by means of a low-cost and portable optoelectronic system, liable to be advanced into a fully automated prototype thanks to an observed trend change in refractive index The system core features a laser diode and a PSD (position sensitive detector), achieving a sensitivity of 46 × 10−4 RIU (refractive index unit) on discrete samples, a similar figure to those reported by instruments utilized by enologists The prototype has been validated with model solutions as a prior step toward the monitorization of the must fermentation in a laboratory fermenter Consequently, it represents an alternative method to traditional areometry for recording the fermentation evolution
