   A Design of Solid State Power Controller for a bidirectional DC-DC Converter in an aeronautic context
By Hassan CHEAITO [View]

Abstract: This paper deals with the design of a solid state power controller (SSPC) for a DC-DC converter in an aeronautic application. First, the specifications are drawn appropriately with the aeronautic environment. Then the design and experimental validation are described.

   A HIGH-EFFICIENCY CONTROL OF A DOUBLE-INPUT CONVERTER FOR RENEWABLE ENERGIES AND HYBRID VEHICLES
By Mario MARCHESONI [View]
[Download]

Abstract: A double-input DC-DC converter is taken into account in this paper. The converter is bidirectional and both currents can be controlled independently. On the one hand it allows to reduce the number of switches, on the other hand, it exhibits a higher efficiency in comparison to a traditional solution with two half-bridge converters in parallel connection. However, the control strategy proposed in the technical literature forces the converter to work in Continuous Conduction Mode at low-load, which leads to a low conversion efficiency. In this paper, a novel control, which exploits Discontinuous Conduction Mode, is presented. Efficiency increase is evaluated with a thermal model in MATLAB/Simulink Plecs environment and the control algorithm is then validated with experimental tests on a converter prototype.

   A new Approach of Resonant Converter using Large Air Gap Transformer
By Michael FINKENZELLER [View]
[Download]

Abstract: A major topic of resonant converter is the need of additional resonant tank components. The use of stray inductance of a conventional transformer for this purpose is very limited. For high power and high frequency applications these additional components are challenging and have low acceptance due to its additional costs. For a high efficiency and to cover the whole operating area a well-considered design with respect to ZVS capability from zero to full load range is essential. In this paper, a new Large Air Gap Transformer is proposed which includes all inductive resonant tank elements for series-parallel resonant converter and the transformer in a single component. This simple design is very easy to handle but still operates in the full operating area and high efficiency. A reduction about 80 \% of ferrite material is achieved by using this new Large Air Gap Transformer. A field simulation to exclude possible electromagnetic interactions with the environment has been carried out. The new approach is demonstrated with LLC converter based on SiC with 10 kW output power and 200 kHz switching frequency.

   Using a web scraping algorithm for component model generation in multi-objective optimization of power electronic applications
By Marcel GLADEN [View]
[Download]

Abstract: The component-model-creation process for multi-objective optimization tools in power electronic applications has been rarely investigated in literature. In this work, a new approach to model creation is shown, which includes public internet information and a web scraping technique. Web scraping is known from data science. It is a possibility to extract data from websites in real time and to save information into a desired data format. This publication first introduces the basics of web scraping and shows how it can be applied to the generation of power electronic component models. The "PFC choke" is used as an example in this paper. The component cost models, the size and efficiency models for two different choke series are generated using web scraping. It is discussed whether it makes sense to create a model for both series or whether one model should be created for each series. Finally, all models are parameterized so that they could be integrated directly into a virtual prototyping routine. The approach can be used universally for every power electronic component.
