In the technique proposed, a full order FE model is transformed into a user specified (or error determined) reduced order system using empirical eigenvectors (EE). The EE method uses an observation of the response of a full model to construct a reduced basis that replicates a full system. Nonlinear attributes resulting from saturation are naturally preserved in the reduction, while the numerical effort required to model the component is greatly reduced. The EE method has been applied to model an iron-core toroidal inductor. A four-fold increase in the speed of computation has been obtained for a linear, fixed time step analysis and a seventy-one fold increase for a nonlinear, variable time step analysis, without observable loss in accuracy.","PeriodicalId":137483,"journal":{"name":"2004 IEEE Workshop on Computers in Power Electronics, 2004.

The state equations of a converter change with switching behavior, also called events, which must be determined using an iterative solution. Diode commutation is a prime example that occurs in nearly all complex power electronic circuits. The language examined in this paper, Modelica, was developed for solution of systems with discrete events such as switching. A multiple-input, multiple-output (MIMO) flyback converter has been used as an example, and compared to experimental results.","PeriodicalId":137483,"journal":{"name":"2004 IEEE Workshop on Computers in Power Electronics, 2004.

The main advantage of the proposed method is that studies can be done for any solar array configuration formed from elementary models of solar cell units. Hierarchical structure of solar cell elements with semiconductor detail allows simulations of electrical properties as well as evaluation of environmental conditions impact. Application examples such as the effect of unequal illumination on various array interconnections and the mismatch of solar cells are presented to demonstrate the usefulness of the tool. The automated process eases investigation of large system and worst-case study for given environmental scenarios.","PeriodicalId":137483,"journal":{"name":"2004 IEEE Workshop on Computers in Power Electronics, 2004.

The system uses a fully software reconfigurable processing core based on a powerful DSP and FPGA and a limited set of well-specified functional hardware blocks. Three examples using the same hardware in diverse areas of power electronic control demonstrate that this technique allows the implementation of demanding state-of-the-art power electronics systems, with the important benefit of a much reduced development time and increased reliability.
