Title: Immersion Cooled Power Electronic Converters – Modeling, Simulation, and Testing Validations

Abstract: Thermal management plays a critical role in the performance of power electronic converters, which is closely related to the efficiency, power density, reliability, and cost of the overall power converter systems. Immersion cooling, as an emerging thermal management approach for power electronics, has received increasing attention in recent years, across numerous industry sectors, such as data center, electrified transportation, energy storage, and many others. Immersion cooling enables dramatic enhancement not only on thermal management, but also on dielectric insulation, especially for high-voltage power converter systems. In this tutorial, the concept of immersion cooling for power electronics will be introduced, followed by multi-physics modeling, simulation, and testing validation of various power converters, based on the speakers’ recent research outcome from an industry-sponsored project.
