Digital Twin Based Automated Design for Converters Incorporating Wide-Band Gap Devices

Abstract:

Future power electronics systems are bound to be based on the emerging wide band gap devices. Increased temperature robustness, blocking voltage and shorter rise times are the main cause for ongoing trends. Due to the latter, combined with a significant size decrease, content of signals frequency enters GHz range obstructing measurement accuracy and even the possibility of measuring signals without influencing the system. This leads to an unprecedented situation, in which simulation tends to yield higher accuracy and result robustness, than experimental measurements in the RF range. For this reason Digital Twin approach to design seems to be an appropriate response to present challenges, allowing not only for a reduction of prototyping cycles but also providing more detailed and comprehensive data. Furthermore, the generated data can be used for design optimization and automation lowering time-to-market and increasing the robustness of design process even further while providing higher-quality end products.
