ADVANCE PROGRAM

CAIRNS, AUSTRALIA33RD IEEE POWER ELECTRONICS SPECIALISTS CONFERENCE Cairns Convention CentreCairns, AustraliaJune 23-27, 2002Sponsored byIEEE Power Electronics Society ADVANCE PROGRAMT ECHNICAL P ROGRAMT UTORIAL S ESSIONSSunday, June 23 Cairns Convention Centre Tutorial 1: Restructuring of Power Electronics and Electric Machines/Drives Courses that has Significantly Increased Student EnrolmentsCairns Convention Centre 8:30 am - 12:00 noon Presenter: Ned Mohan, University of Minnesota, Minneapolis, USAIn this seminar three approaches to the teaching of power electronics and systems will be presented.A Building-Block Approach to Switch-Mode Power Electronics. All practical switch-mode converter topologies are derived from a switching power pole, showing their commonality. As a two-port system, with a voltage-port on one side and the current-port on the other, representing this power pole on an average basis as a controllable turns-ratio ideal transformer gives clear insight into waveform synthesis by PWM.An Integrative Approach to Teaching of Electric Drives as a First Course. This allows the teaching in a single semester of all subsystems that make up electric drives: electric machines, power electronics-based converters and feedback controllers. The use of space-vector theory, made approachable to undergraduates, reveals the physical basis of how ac machines operate and provides a clear understanding of how they ought to be controlled.Integration of Simulation and Hardware. In power electronics courses, use of PSpice will be demonstrated for analysis and design of converters and their control. Use of MATLAB and Simulink will be demonstrated for simulating electric drives, and for integrating a DSP-based, 42-V hardware laboratory (in which nearly 70 US universities have shown interest in collaboration) for electric drives and power electronics.Tutorial 2:Structures, Operations, and Applications of Fuel Cells and Their Power Electronics InterfaceCairns Convention Centre 8:30 am - 12:00 noon Presenter: A. Emadi, Illinois Institute of Technology, USA In this tutorial, structures, operations, and characteristics of different fuel cells are presented. Major types of fuel cellsincluding Proton Exchange Membrane Fuel Cells (PEMFC), Alkaline Fuel Cells (AFC), Solid-Oxide Fuel Cells (SOFC), Phosphoric Acid Fuel Cells (PAFC), Molten Carbonate Fuel Cells (MCFC), and Direct Methanol Fuel Cells (DMFC) are explained. Their applications in the automotive industry including electric and hybrid electric vehicles, in the aerospace industry, in utility systems including distributed generation and cogeneration, in residential and commercial buildings, and in portable devices are described as well. In addition, current status and future trends in the areas of power electronics for fuel cell applications will be explained. Power electronics plays an important role in providing an interface between the fuel cell and the load. Furthermore, power electronic converters ensure that the power is reliably and efficiently delivered to the load in the required DC or AC forms.. In this tutorial, we present a review of power electronic converter topologies for fuel cell applications.Tutorial 3: Harmonic Treatment in Industrial Power SystemsCairns Convention Centre 1:30 pm – 5:00 pm Presenter: S.N. Manias, National Technical University of Athens, GreeceIn this tutorial the following material will be presented:Introductory definitions; real power, reactive power, distortion power, total power, real power factor and THD%. Categories of Power Quality variations. Disturbances. Steady-State variations that include normal RMS voltage variations and harmonic distortion. Harmonic distortion sources in industrial power systems such as Adjustable Speed Drive Systems (ASDs), other converter equipment, voltage controllers, transformers and arcing loads. Current-Source and Voltage-Source Non Linear Loads. Effects of harmonics on equipment such as distribution transformers, electric motors, circuit breakers, electronic equipment, conductors, telephone equipment etc. Harmonic measurements in industrial power systems using state of the art equipment for high frequency measurements; current transformers, voltage transformers, clamp-on current transformers, Hall Effect Probes, Voltage Probes, Harmonic Analyzers and Output Formats. Evaluation of the harmonic measurements. Comparison of harmonic standards (IEEE-519-1992, EN501 60 etc.).Harmonic Mitigating Techniques; passive filters, active harmonic compensation, phase multiplication and line reactors. General passive and active filter design procedure. Design Examples. Grounding practices of non linear loads in order to eliminate high frequency circulating current harmonics.Tutorial 4: Low-cost, low-power topologies and energy savings in adjustable speed drivesCairns Convention Centre 1:30 pm – 5:00 pm Presenter: Frede Blaabjerg, Aalborg University, DenmarkThis tutorial will give a broad overview and an in-depth analysis of the possibilities to have low cost topologies in single- and three-phase motors. It will also discuss the possibilities to save energy in adjustable speed drives with induction motors and in some cases permanent magnet motors. The typical power range will be below 10 kW.The low-cost topologies include B2 - B4 - B6 inverters with different modulation strategies for torque-ripple reduction. Discussion will include how a combination of topology and modulation can reduce the number of sensors.Models of induction and permanent magnet motors will be used to derive control methods to improve the efficiency of the whole drive. Stability of the drive and implementation aspects are explained. The potential energy saving in different applications will be discussed. Different drive systems will be compared both in type and power rating. Aspects with respect to harmonic reduction techniques will also be included with solutions based on both equipment and system analysis presented. Cost benefit analysis of the solutions will also be given.Finally, most of the discussed methods will be related to experimental work.P ROBLEM W ISDOM M ODERATION (PWM)Tuesday, June 25 Cairns Convention CentrePWM 1: The Teaching of Power ElectronicsSession Chair: Professor Richard DukeThis PWM Session will concentrate on aspects of teaching power electronics, particularly emphasising the differences that occur around the world. An international panel representing Asia, Australasia, Europe and America will put their point of view and stimulate discussion. Topics for discussion may include, but are not limited to:• What can we learn from each other?• How do we go about sharing resources?• What is the purpose of power electronics laboratories? • Is a knowledge of switching device physics necessary? • How do we bridge the gap between theory and practice?PWM 2:Technical Communications: Fatally Wounded or Just Badly Injured?Session Chair: Dr. Grahame HolmesThis PWM Session will concentrate on ideas for the reform of both conference and journal paper review process, including but not limited to:• quality control of the process• rewards and/or recognition for reviewers• should a reviewer "endorse" the paper?• author appeal process• should PESC be fully reviewed?• Does the recording of academic (or other) advances need to be better organized?• Can we replace "serial" publications (time based) with "keyword" or "topic" based electronic access?PWM 3: Battery and/or energy storage technology Session Chair: Professor Rik De DonckerThis PWM Session will concentrate on energy storage devices and supercapacitors (double-layer capacitors) in particular. Supercapacitors have an order of magnitude increased energy density over normal capacitors, and have greatly increased cyclic capability. In this session, power conversion applications of supercapacitors will be discussed, including limitations, common problems, and areas where particular advantages can be foreseen.T ECHNICAL S ESSIONSM ONDAY J UNE 24S ESSION 1-1:O PENING AND P LENARY P RESENTATIONS24 J UNEM ONDAY 10:40 8:45–Introductionand8:45 WelcomeAddress8:55 OpeningDr. Robin Batterham, Australia’s Chief Scientist9.25 Torque Control of a Spherical Machine withVariable Pole PitchKahlen, K., Voß, I., Priebe, C., De Doncker, R.W, Institute forPower Electronics and Electrical Drives, RWTH, GERMANY9.50 Comparison of Wind Turbines Regarding theirEnergy GenerationMutschler, P., Hoffmann, R., Darmstadt University ofTechnology, GERMANY10:15 Embedded Passives Integrated Circuits for PowerConvertersWaffenschmidt, E.1, Ferreira, J.A.2, 1Philips ResearchLaboratories, THE NETHERLANDS, 2Delft University ofTechnology, THE NETHERLANDS10:40 Morning TeaS ESSION 2-1: H IGH P OWER DC C ONVERTERS11.10 – 12:25 M ONDAY 24 J UNE11.10 Development of High Current Power Supply forElectroplatingPei, Y.Q., Jiang, G.B., Liu, H.T., Wang, Z.A., Xi'an JiaotongUniversity, CHINA11.35 Cascaded DC-DC Converter Connection ofPhotovoltaic ModulesSernia, P., Walker, G., University of Queensland, AUSTRALIA12.00 Parasitic Ring and Design Issues of High PowerInterleaved Boost ConvertersHuang, X.1, Wang, X.1, Ferrell, J.1, Nergaard, T.1, Lai, J.1, Xu,X.2, Zhu, L.3, 1Virginia Polytechnic Institute and StateUniversity,USA, 2Ford Research Lab, USA., 3Ballard PowerSystem Inc., USA12:25 LunchS ESSION 2-2: A MPLIFIERS11.10 – 12:25 M ONDAY 24 J UNE11.10 A Novel Controller for Switching Audio PowerAmplifier with Digital InputPark, J.1, Kim, C.G.1, Cho, B.H.1, Jeong, J.2, 1Seoul NationalUniversity, KOREA, 2Digital and Analog Company Ltd., KOREA11.35 Ripple Feedback Filter Suitable for Analog/DigitalMixed-Mode Audio Amplifier for ImprovedEfficiency and StabilityKim, N.I., Jung, S.H., Ryoo, T.H., Cho, G.H., Korea AdvancedInstitute of Science and Technology, KOREA12.00 A Class-B Switch-mode Assisted Linear AmplifierWalker, G.R., University of Queensland, AUSTRALIA12:25 LunchC ONVERTERSS ESSION 2-3: M ATRIX11.10 – 12:25 M ONDAY 24 J UNE 11.10 Matrix Converter Topology with Reduced Number ofSwitchesWei, L., Lipo, T., University of Wisconsin-Madison, USA 11.35 Short-term Braking Capability During PowerInterruptions for Integrated Matrix Converter-Motor DrivesKlumpner, C., Blaabjerg, F., Aalborg University, DENMARK 12.00 A New Resonant Soft Switching Topology for DirectAC-AC ConvertersBland, M.J., Empringham, L., Clare, J., Wheeler, P., Universityof Nottingham, UK12:25 LunchC ONVERTERSS ESSION 2-4: S ERIES11.10 – 12:25 M ONDAY 24 J UNE 11.10 A Novel Control Strategy for Unified Power QualityConditioner (UPQC)Tarafdar Haque, M.1, ISE, T.2, Hosseini, S.H.1, 1TabrizUniversity, IRAN, 2Osaka University, JAPAN11.35 Dynamic Performance of a Unified Power FlowController for Stabilizing AC Transmission SystemsFujita, H.1, Watanabe, Y.2, Akagi, H.1, 1Tokyo Institute ofTechnology, JAPAN, 2Japan Atomic Energy Research Institute,JAPAN12.00 A Nonlinear Control Method of Dynamic VoltageRestorersChen, S.C.1, Joos, G.J.2, Lopes, L.L.1, Guo, W.G., 1ConcordiaUniversity,CANADA, 2McGill University, CANADA12:25 LunchS ESSION 2-5: W IND GENERATION S YSTEMS11.10 – 12:25 M ONDAY 24 J UNE 11.10 A New Fuzzy Logic Controller to Improve theCaptured Wind Energy in a Real 800 kW VariableSpeed and Variable Pitch Wind TurbinePrats, M.M., Carrasco, J.M., Galvan, E., Sánchez, J.A.,Franquelo, L.G., Batista, C.2, Ángel González, A.G.2, Hurtado,S.H.2, 1Escuela Superior de Ingenieros, SPAIN, 2MADETecnologías Renovables SA, SPAIN11.35 New Formula to Determine the MinimumCapacitance Required for Self-Excited InductionGeneratorEltamaly, A., Elminia University, EGYPT12.00 A Reliable and Efficient New Generator System forOffshore Wind Farms with DC Farm GridHenschel, M., Hartkopf, T., Schneider, H., Troester, E.,Darmstadt University of Technology, GERMANY12:25 LunchC OMPONENTSS ESSION 2-6: P ASSIVE11.10 – 12:25 M ONDAY 24 J UNE 11.10 Embedded Capacitance in the PCB of SwitchmodeConvertersFerreira, J.A.1, Waffenschmidt, E.3, Strydom, J.2, Van Wyk, J.D.2,1Delft University of Technology, THE NETHERLANDS, 2CPES,Virginia Polytechnic Institute and State University, USA,3Philips Research, GERMANY11.35 Using Supercapacitors to Improve BatteryPerformanceSmith, T.A., Mars, P., Turner, G., Cap-XX Pty.
