  • Phenomena of Perturbation in Electrical Systems
    Chapter 1 Phenomena of Perturbation in Electrical Systems 1.1. Electromagnetic perturbations in energy systems 1.1.1. Introduction Power electronic systems are increasingly being used in every field; initially, they were used in the industrial sector and then used increasingly in transportation, services and housing sectors. The flexibility in the control of electrical energy explains this evolution well. For the purposes of illustration, we estimate that the electrification of service or control functions in an aircraft offers the following gains1: – 10% on the mass; – 9% onCOPYRIGHTEDfuel consumption; MATERIAL – 13% on thrust from the engines; – 15% on maintenance costs; – 10% on the buying price. 1 According to SAFRAN company, symposium SPEC 2007. 2 Electromagnetic Compatibility in Power Electronics The field of automobiles is also subject to this evolution: the development of hybrid vehicles over the last 10 years and, more recently, the re-emergence of the fully electric car (while waiting for fuel cells vehicles) are evidence of this. Already, a large number of services have been electrified in thermal engine automobiles because of the flexibility of controls (speed variation) and high yield of the electrical systems: power steering, anti-blocking system (ABS), various pumps, window winders, air conditioning (to come). The introduction of this technology, as a consequence, must take into consideration its implementation constraints; electromagnetic compatibility (EMC) in particular. Indeed, static converters based on power electronics are important sources of electromagnetic perturbations that can occasionally cause malfunctions in their local or distant electronic environment: avionics, navigation systems, reception antennae, etc. Thus, it is important to understand the origin of these phenomena, their mode of propagation and the effects on their potential “victims” in order to optimize the essential reduction or protection devices necessary to conform to the standards of EMC.

Special thanks to David Kachmarik, Dr. Louis Nerone, and Timothy Chen for guiding me throughout the thesis and my time at GE lighting. I would also like to thank Dr. F.E. Villaseca and Dr. Dan Simon for their valuable suggestions for my thesis. Finally, endless thanks to my family for supporting me to gain a higher education. DISCRETE DIMMING BALLAST FOR LINEAR FLUORESCENT LAMPS HAIYAN WANG ABSTRACT A new discrete dimming ballast for the linear fluorescent lamps is proposed in this paper. The dimming control circuit is combined with a ballast module for multiple lamps to realize three discrete lighting levels control. Compared with conventional step dimming or odoff control methods, the proposed discrete dimming method has following advantages: (1) Digital signal is generated by the dimming control circuit to control the lamps on and off, which makes the system more reliable and integrated. (2) The proposed discrete dimming system replace the relays, which are necessary in conventional lamp on/off control, and decrease the system cost. (3) The proposed dimming ballast can be installed by keeping the original wiring system. This makes the upgrading lighting system more effective and efficient.

All Rights Reserved. 2 This thesis titled CO 2 Mass Transfer in a Novel Photobioreactor by ADAM MIELNICKI has been approved for the Department of Chemical and Biomolecular Engineering and the Russ College of Engineering and Technology by David J. Bayless Loehr Professor of Mechanical Engineering Dennis Irwin Dean, Russ College of Engineering and Technology 3 Abstract MIELNICKI, ADAM, M.S., August 2011, Chemical Engineering CO 2 Mass Transfer in a Novel Photobioreactor Director of Thesis: David J. Bayless A novel carbon capture and storage (CCS) technology at the center of this investigation involves the biosequestration of CO 2 via cyanobacterial photosynthetic processes. A simulated flue gas stream introduces CO 2 into a temperature controlled photobioreactor where cyanobacteria are nourished with a flowing growth solution. Before the microorganism can fix carbon, CO 2 has to dissolve in the liquid growth solution. The absorption of CO 2 presents a potential limiting step in cyanobacterial growth and is therefore in need of quantification. In this study, the effects of growth solution flow rate on the liquid side mass transfer coefficient (k L) were observed and a model was selected for k L prediction. Both the model and experimental data showed that k L tends to increase with flow rate. Gaseous CO 2 concentration was manipulated as well and was shown to affect overall mass transfer but not k L.

The acquisition It is the first Saturday of august, 2008 and I am browsing a familiar exhibition for old technology in the small town Hoenderloo. Aside from some parts I had not yet made any purchases and was about to head home, when I laid my eyes on a radio set that I did not immediately recognize. The Erres-buttons instantly caught my attention. The set had endured a lot and the back wall of the casing was missing. The nameplate indicated that this was the KY 159 (serial number 1161) made in 1936 and after some negotiating the device changed hands. At home, the radio set was more thoroughly inspected. This turned out to be a letdown... Picture 1.1 The casing looked a lot less flourishing than it looked on the sunny market stand. The damage to and stains on the casing would not give in to basic cleaning and scrubbing. In some occasions furniture oil can provide a great result, which would make stripping, coloring and varnishing not necessary. Unfortunately this was not the case (picture 1.1). A quick look at the interior did not make my heart skip a beat either.

  • Piezoelectric Inertia Motors—A Critical Review of History, Concepts, Design, Applications, and Perspectives
    Review Piezoelectric Inertia Motors—A Critical Review of History, Concepts, Design, Applications, and Perspectives Matthias Hunstig Grube 14, 33098 Paderborn, Germany; [email protected] Academic Editor: Delbert Tesar Received: 26 November 2016; Accepted: 18 January 2017; Published: 6 February 2017 Abstract: Piezoelectric inertia motors—also known as stick-slip motors or (smooth) impact drives—use the inertia of a body to drive it in small steps by means of an uninterrupted friction contact. In addition to the typical advantages of piezoelectric motors, they are especially suited for miniaturisation due to their simple structure and inherent fine-positioning capability. Originally developed for positioning in microscopy in the 1980s, they have nowadays also found application in mass-produced consumer goods. Recent research results are likely to enable more applications of piezoelectric inertia motors in the future. This contribution gives a critical overview of their historical development, functional principles, and related terminology. The most relevant aspects regarding their design—i.e., friction contact, solid state actuator, and electrical excitation—are discussed, including aspects of control and simulation. The article closes with an outlook on possible future developments and research perspectives. Keywords: inertia motor; stick-slip motor; smooth impact drive; piezeoelectric motor; review 1. Introduction Piezoelectric actuators have long been used in diverse applications, especially because of their short response time and high resolution. The major drawback of these solid state actuators in positioning applications is their small stroke: actuators made of state-of-the-art lead zirconate titanate (PZT) ceramics only reach strains up to 2 . A typical piezoelectric actuator with 10 mm length thus reaches a maximum stroke of only 20 µm.h Bending actuator designs [1] and other mechanisms [2] can increase the stroke at the expense of stiffness and actuation force ([3]; [4] (pp.

The current-to-torque and frequency-to-speed relationships of BLDC motors are linear. BLDC motors may be described as stepper motors, with fixed permanent magnets and possibly more poles on the rotor than the stator, or reluctance motors. The latter may be without permanent magnets, just poles that are induced on the rotor then pulled into alignment by timed stator windings. However, the term stepper motor tends to be used for motors that are designed specifically to be operated in a mode where they are frequently stopped with the rotor in a defined angular position; this page describes more general BLDC motor principles, though there is overlap.
