   A Simple And Efficient Parameter Extraction Procedure For Physics Based Igbt Models
By Rui Chibante, Armando Araujo, Adriano Carvalho [View]
[Download]

Abstract: Extraction of parameters for models of power semiconductors is a need for researchers working with development of power circuits. One of the drawbacks of physics based models is how to extract the numerous parameters to describe the model. Different approaches have been taken, most of them cumbersome to be solved. This paper presents a simple and accurate method of parameter extraction for physics based IGBT models. The procedure, based on an optimization algorithm (simulated annealing), is easy to implement and is efficient for extraction of a large number of parameters needed for physics based IGBT models, only requiring some experimental points of DC and resistive load characteristics. It is validated by comparing experimental and simulated results, at various operating conditions, using a Finite Element, physics based, IGBT model.

   Half-Order Modelling Of Supercapacitors
By Delphine M. Riu, Nicolas R. Retiere [View]
[Download]

Abstract: This paper presents a new approach to model the dynamic behaviour of supercapacitors using half-order systems. The new model is determined in the frequency domain but a Matlab model can also be defined for simulating the voltage response and energy efficiency e.g. for automotive power systems.

   Planar Pcb-Based Transformers Method Of Calculation And Design Study
By Stephan Schuh, Manfred Albach [View]
[Download]

Abstract: The miniaturization of transformers is one of the interesting projects to obtain a space reduction of classical circuits. Therefore it is necessary to investigate new concepts. PCB-based transformers with FPC-layers (Ferrite Polymer Compounds) as magnetic core have acceptable parameters and provide the possibility of an ultra flat design. An optimisation of these transformers under several parameters is possible based on the presented calculation method. Additionally various possibilities for the transformer design are presented and compared to each other. Simulations and measurements are used to verify the predicted results.
