“…The major problem is simulation speed. If only considering short term high dissipated power effects like short circuit condition [41] and [42], instantaneous power loss based simulation is the only method available. However in these cases the long thermal time constants were not required.…”

The development of a fully automated tool that is used to optimize the design of a hybrid switch soft-switching inverter using a library of dynamic electro-thermal component models parameterized in terms of electrical, structural and material properties is presented. A multi-scale electro-thermal simulation approach is developed allowing for a large number of parametric studies involving multiple design variables to be considered, drastically reducing simulation time.Traditionally, electro-thermal simulation and analysis has been used to predict the behavior of pre-existing designs. While the traditional approach to electro-thermal analysis can help shape cooling requirements and heat sink designs to maintain certain junction temperatures, there is no guarantee that the design under study is the most optimal. This dissertation uses electro-thermal simulation to guarantee an optimal design and thus truly minimizing cooling requirements and improving device reliability.The proposed optimization tool is used to provide a step-by-step design optimization of a twocoupled magnetic hybrid soft-switching inverter. The soft-switching inverter uses a two-coupled magnetic approach for transformer reset condition [1], a variable timing control for achieving ZVS over the entire load range [2], and utilizes a hybrid switch approach for the main device [3].

“…In such analyses, SPICE software is very helpful and is used very often [11,35]. The degree of complexity of the considered system means there is no reason to use the scheme of this system or introduce the models of components of this system to proper places, because this would lead to an unacceptably long duration of computations or even problems in obtaining the convergence of computations [36]. Therefore, it is advisable to elaborate a supplementary diagram of the considered system in the form of a macromodel for SPICE software.…”

This article proposes a model of an actual photovoltaic installation situated in the Gdynia Maritime University, Poland. This model is formulated in the form of a SPICE network. In the presented model, the influence of selected weather parameters and thermal phenomena on the properties of the components of this installation are taken into account. The structure of the analyzed installation and the form of the formulated model are both presented. By means of this model, values of the power produced by the installation considered in different seasons and different times of the day are computed. The obtained computation results are compared to the measurement results. Good agreement between the results of measurements and computations is obtained. The obtained results of the investigations confirm the considerable influence of weather conditions, as well as daily and seasonal changes in solar irradiation and the ambient temperature, on the electrical energy produced. In the summer months, a decrease in the energy efficiency of the conversion of solar energy into electrical energy in comparison to the winter months is also visible and can even be twofold.

“…Currently, engineers use computer programs, e.g., SPICE or PLECS, to design and analyze power electronic circuits [10][11][12]. Practical usefulness of the obtained results of computations depends on, e.g., accuracy of the models of applied elements contained in these circuits [13]. Therefore, models of the considered components characterized by a different accuracy are given in the literature.…”
