Presentation Description: There are many types of DC-DC power electronic converters with simple to advanced topologies, such as the simple unidirectional flyback converter to the advanced ones as those used for robust bidirectional operation. The seminar will focus on the design procedures and calculation for high-power converters which have the capability of bidirectional power delivery and conditioning. At its intermediate level it will cover the common non-isolated and galvanically isolated converters, namely, the high-power buck-boost and chopper converters in addition to the DABs DC converters.
The seminar will start with a brief introduction to the most common DC-DC converters covering their characteristics and their cascaded and parallel structures for mobility systems. Then it will cover modelling aspects of the converters for design and calculation of their components step-by-step including power-loss evaluation for thermal management, based on analysis, specifications, and worst-case operational scenarios.
Finally, the presenter will demonstrate the stages for estimating the efficiencies of the considered converters with results, which help in the process of selecting the most favourable converters in terms of power-loss reduction and performances.
