   Modeling, Analysis and Simulation of Single Phase Induction Machines With Position-Dependent Loads
By A.M. Stankovic; H. Liu [View]
[Download]

Abstract: The paper presents development and validation of a dynamical model and an equivalent circuit for a single-phase induction machine supplying a position-dependent load. The problem has a major industrial significance, as it arises in a number of applications, such as compressors in airconditioning systems. Conventional models are not accurate enough for basic design studies like efficiency calculations, necessitating laborious time-domain simulations that reveal little about the sensitivities to design parameters. The proposed solution is based on dynamic phasors, which is a systematic methodology for derivation of low-order nonlinear models for energy conversion systems.

   SIMULATION - An Essential Tool in Modern Switch Mode Power Supply Design
By Tero Järveläinen; Mikko Kuisma; Pertti Silventoinen [View]
[Download]

Abstract: Today¡¦s powerful computers and programs provide many useful and cost effective solutions in the design flow of switch mode power supplies (SMPS). Somehow it still seems that design engineers in the industry are frightened of these new possibilities and the design of a new product is made ¡§the familiar way like in the 70¡¦s¡¨. Two different kinds of simulation approaches are presented in this paper. An example design procedure of AC/DC SMPS is made with a system level simulator, MathWorks MATLABÆÊ and SimulinkÆÊ. Also some circuit level simulation is made with OrCAD PSpiceÆÊ and comparison of main differences and problems in different types of simulation tools is made. The accuracy of the simulation results and applied models is compared with measurements made with the prototype.

   Simulation and Verification of a Hybrid Bus
By C. Andersson; K. Jonasson; P. Strandh; M. Alaküla [View]
[Download]

Abstract: A simulation model of a Hybrid Electric Bus (HEB) is presented in this paper. The model is verified through an existing HEB equipped with a measurement system. Finally some alternatives charging strategies and their consequences for the real HEB are presented.

   Flexible Drive Systems Laboratory – A Modern Teaching Facility in Electrical Drives at Aalborg University
By R. Teodorescu; M. Bech; F. Blaabjerg; J.K. Pedersen [View]
[Download]

Abstract: A new approach in teaching electrical drives is achieved at the Flexible Drives System Laboratory (FDSL) from Aalborg University by using the new Total Development Environment (TDE) concept that allows a full visual block-oriented programming of dynamic real-time systems to be done using the Matlab/Simulink environment. Basics in Electrical Drives and Advanced Control of PWM Inverter Fed Induction Machines courses are using the new facility and an increased student enrollment is expected in the next coming years.
