DOWNLOAD EBOOKComputer-aided design has come of age in the magnetic devices industry. From its early beginnings in the 1960s, when the precision needs of the experimental physics community first created a need for computational aids to magnet design, CAD software has grown to occupy an important spot in the industrial designer's tool kit. Numerous commercial CAD systems are now available for magnetics work, and many more software packages are used in-house by large industrial firms. While their capabilities vary, all these software systems share a very substantial common core of both methodology and objec tives. The present need, particularly in medium-sized and nonspecialist firms, is for an understanding of how to make effective use of these new and immensely powerful tools: what approximations are inherent in the methods, what quantities can be calculated, and how to relate the com puted results to the needs of the designer. These new analysis techniques profoundly affect the designer's approach to problems, since the analytic tools available exert a strong influence on the conceptual models people build, and these in turn dictate the manner in which they formulate prob lems. The impact of CAD is just beginning to be felt industrially, and the authors believe this is an early, but not too early, time to collect together some of the experience which has now accumulated among industrial and research users of magnetics analysis systems.

DOWNLOAD EBOOKThe increasing complexity of power electronic devices requires the intervention of computer-aided design in electrical engineering. Development of electric/electronic systems nowadays is carried out by the help of virtual prototyping, in which simulation software are used to predict components behavior without investing time and money to build physical prototypes. The increasing demand of low power, high efficiency devices forced designers to precisely analyze losses in each component constituting the system. Magnetic components constitute a major part of electronics devices. Therefore accurate modeling of magnetic materials is mandatory in order to predict their realistic behavior under variable operating conditions. Our work takes place in this context by proposing a non-linear dynamic model of magnetic components for use in circuit simulators. It includes the material nonlinear hysteretic and dynamic behaviors with accurate modeling of winding and core losses in addition to thermal effects that are not taken into account by existing models. The model is based on the principle of separation of static and dynamic contributions as well as Bertotti's theory. VHDL-AMS is used as a modeling language due to its multi-domain modeling feature, allowing coupling with a thermal model. The magnetic component model is implemented in circuit simulation software “Simplorer” It is then tested in a widely used power converter application, the buck converter, to ensure non conventional excitation. The model is validated for different core inductors, different current ripples, different loads, different temperatures and a wide frequency range.

DOWNLOAD EBOOKThe aim of this special volume was to facilitate the exchange of information concerning the best practices for CAD, CAM, Manufacturing, Mechanical Engineering, Modeling and Simulation, etc. It provided the opportunity for engineers and scientists in academia, industry, and government to address the most innovative research and developments, including technical challenges, social and economic issues, and to discuss ideas, results, work-in-progress and experience touching all aspects of Computer-Aided Design, Manufacturing, Modeling and Simulation. Review from Book News Inc.: The 140 papers selected for the September 2011 conference share research on advanced manufacturing technology, modeling nanosystems, intelligent design, adaptive control, scheduling, and power electronics. The second volume of the two-volume set focuses on software development, system optimization, vibrations and dynamics, sustainable materials, and virtual manufacturing. The Chinese contributors propose a feature extraction method for mechanical part recognition, an assembly matrix for aircraft components, a boiler temperature field reconstruction algorithm, and an absolute magnetic grid displacement sensor. Other topics include heat and moisture transfer in environmental clothing, wind turbine blade design, mine emergency rescue paths, and digital watermarking for CAD models. B & w images are provided.
