Samenvatting van het onderzoek / Summary of Research
Because of the increasing applications of power electronics such as building integrated photovoltaics, electric cars and DC microgrids, the demand for and demands on power electronics have increased over the recent years. Simultaneously, research and developments on the active switches and passive filter components used in these converters have increased. This expands the possible design choices and objectives, making the search for optimal solutions more challenging.
This work therefore focusses on design methodologies for two of the components in typical converters: the passive inductive components and the active switching components. The goal is to find optimal solutions according to multiple objectives such as volume and efficiency. Combining fast models, innovative simulation methods and automated optimisation algorithms, powerful tools are developed and demonstrated in this work. For the inductive components, the design method can be used to quantify the impact of certain design choices, such as materials and cooling, in the form of objectives such as power loss and volume. For the active switches, detailed SPICE models are generated from generally available datasheet parameters. Combining measurements with these SPICE models, allows for the identification of potential problems with the specific design of the converter, while simultaneously increasing the accuracy of the model.
The outcome of this work is a set of powerful tools for designers of power electronic converters, to help in the design of the most challenging aspects of the converter. These are required to improve typical demands on power electronics such as efficiency, volume and weight in the vast amount of old and new applications, while more technological options become available.
