Abstract
Electric power conversion apparatuses such as electromagnetic transformers and power electronic converters play a backbone role in the global power and energy industries, such as power transmission and distribution, electrified transportation vehicle systems, industry automation, and the like. To investigate the performance (efficiency, reliability, etc.) of such critical power conversion apparatuses, high-fidelity multi-physics modeling becomes critical which involves dedicated coupling among multiple physical domains, including electrical, magnetic, thermal, mechanical, and material engineering. Nevertheless, the majority of the existing models for these power conversion apparatuses focus only on one or two physical domains, and the modeling fidelity needs to be further enhanced. Targeting at immersion cooled electromagnetic transformers and power electronic converters, this dissertation aims to develop a high-fidelity comprehensive multi-physics modeling approach, to thoroughly investigate the reliability and efficiency of these two apparatuses. The proposed modeling approach can be extended to many other power conversion components and systems.
