A computer-aided simulation of a synchronous machine is described with respect to applications for power electronics. The model is written in the modeling language MAST and will be used for analysing transients. Starting from data sheet values the process of generation of the model parameters is described. A two axes rotor fixed description of the machine is used to get the mechanical behavior. Finally the three phase currents are calculated out of the two axis model by the inverse Park transformation. Modelling results are shown.

This paper presents models for two DMOS devices, the low-voltage lateral diffused MOSFET for IC applications (LDMOS) and the discrete vertical diffused power MOSFET (VDMOS), both developed using the lumped-charge methodology. The LDMOS model gives better performance than the BSIM3 which is the industry-standard model for the lateral diffused MOSFET. The VDMOS model is an improved version of the Budihardjo-Lauritzen model.

This paper describes work using computers to elucidate aspects of the design of class DE DC-DC converters. Class DE is a relatively new type of converter arrangement, whose advantages relate to efficient operation (low switching loss) at megahertz frequencies. Its disadvantages relate to control, and to matching between inverter and rectifier. These are the issues investigated in the paper. In order that the work should be easily accessible to others, readily available packages such as Maple((R)) and Excel((R)) have been used.

A PSpice model of punch through IGBTs based on a physics equation model is presented in this paper. A simplified way of implementing the complicated equations into the PSpice simulator is developed using a mathematical approximation. Also, a new method to elaborate the PSpice netlist is reported. The resulting PSpice model permits simulation on PCs of a physics-based model, which previously required that it be simulated using particular software tools and a powerful hardware platform. Simulations have been performed in order to prove the effectiveness of this method in translating the physics based model in a PSpice netlist.

The basis of a CAD approach for the sizing of a static converter is presented: it lays on the translation of the sizing problem into a constrained optimisation problem. The paper mainly focuses on the way to carry out this translation with computer techniques, and it shows how symbolic methods are powerful in such an approach. With this aim, the paper presents: the optimisation problem, the way to solve it, our approach and our choice, and an example of a sizing problem treated with our methodology.

Efficient variable-speed drives are becoming more and more common in today's industry. Modern drives include efficiency optimization to improve the performances. Different approaches, such as model based and power measure based methods can be adopted. With increasing harmonic pollution in the power system, real-time monitoring and analysis of harmonic variation have become important. In this paper a digital implementation of a high performance 1.5 kW induction motor drive is presented. The system is useful for optimizing efficiency and evaluating harmonic pollution at different speed and load conditions with several optimisation algorithms. Experimental results demonstrate the performance of the proposed drive.

With magnetic components probably being the most critical components in power electronics devices, it would be good to have a simulation tool able to model the high-frequency effects that are sometimes responsible for an efficiency variation of several points. This paper presents a design tool (UO-M/sup 2/T) that offers such a capability without the need of using finite-element analysis tools. The tool allows magnetic component designers to know the behaviour of the elements they devise even before winding them. By defining the exact winding disposition in the core chosen, designers can visualize the transformer or inductor response when an AC sweep is carried out. This will allow them to carry out short-circuit and open circuit tests before winding the transformer.
