An Investigation into the Thermal Benefits of Multilevel Converters [PDF]
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018 This paper investigates the benefits of distributing thermal load across multiple devices on a single heatsink, with a focus on how this might be a benefit in the use of multilevel converters. The analysis uses finite element modelling to derive trends in performance, which combined with real world data permits for a bulk analysis in to whether ...
