In recent years, power electronics have become a key enabling technology within electrical distribution networks, supporting the use of many other novel technologies. They also have a considerable impact though, on the configuration and operation of the electrical networks. Accurate simulations are hence required to aid the development and understanding of these networks. However, simulations using switched power electronics models can be very time consuming, and most power electronics modeling simplification techniques fail to give accurate results for specific systems-level studies. New model simplification methods must be developed in order to facilitate accurate and time efficient systems level simulations.

Modeling of power electronic converters does not lend itself to many traditional circuit simulators such as SPICE. 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.

A thermal model for the CPES IPEM Gen. II is presented. The selected approach is the simulation of the thermal behavior of an experimental IPEM testbed using the ID finite difference method. An equivalent electrical network representation of the thermal behavior of the IPEM is developed using a ID finite approach. The SABER circuit simulation tool is used to verify the behavior of our network model and compare its results with previously acquired temperature measurements from the experimental testbed. Both experimental and simulated responses are presented and compared.

An approach for simulating linear switched networks, such as certain models of power converters, is given. The approach applies the principle of multi-resolution simulation. A full, detailed model is constructed from which a reduced order model is automatically extracted. The bandwidth of the reduced order model can be specified and changed at the users' discretion, even during a simulation run, yielding multiple resolutions and simulation speeds. The method is demonstrated on a simple power converter circuit.

The paper describes a tool developed to automate the study of solar array configurations using a general-purpose simulator such as Spice. 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.

This paper describes a rapid development system that was used to speed up implementation and testing of a number of grid-coupled power electronic systems. 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. It also proves to be an excellent tool in power electronics courses.
