Schedule: 9 a.m. to 4 p.m.
Progress in power electronics (PE) nowadays is an important source of innovation in the fields of drive technology and automation engineering. The development is characterized more and more by miniaturization of electrical systems, standardization and integration of PE into the actuation/drive system. To keep pace with this trend, simulation also here becomes step by step a key technology. Otherwise the most of wide spread commercial simulation tools on the market have their roots not in power electronics. There are often limits and difficulties to use them efficiently in this technical field. So modeling and simulation of large PE systems often lead to huge calculation times and numerical convergence problems. However, the mathematical algorithms of the SIMPLORER simulation approach introduced here, are adapted to such systems perfectly. The result is an unusually high numerical stability, paired with a high calculation speed. There are introduced and discussed comprehensive libraries of power devices, standard electronic components and function blocks (including common structures for rectifiers and inverters, supplies and loads, control elements, motor and transformer models), that make the design of PE systems very efficient.
Further with the tutorial the authors will go into details on methods of modeling dynamic and thermal behavior of power semiconductors. Starting point is a basic knowledge about these devices. The aim of the modeling strategy applied here, is to have a scalable model complexity due to the application. The different model levels are designed to fulfill various requirements of circuit analysis, beginning from paralleling several chips in one package up to taking into account complete PE controlled drives.
In contrast to earlier publications, the new trends in semiconductor development (packaging, higher integration) require a more comprehensive consideration of parasitics and implemented additional functions. Various modeling and simulation examples are illustrated by means of SEMIKRON power semiconductor models.
Last but not least VHDL-AMS Modeling and simulation for PE systems will be discussed. A new low cost VHDL-A simulator kernel will be introduced. VHDL-AMS is a upcoming hardware description language supporting the description and simulation of digital, analog, and mixed-signal systems in a single language. VHDL-AMS stands for Very-High-Speed IC Hardware Description Language - Analog and Mixed Signal. The language is divided into two IEEE standards, Std 1076 and the newer Std 1076.1, which provides analog and mixed signal extensions to the 1076 version.
