Thermal Measurement of Asymmetric Losses in a Submodule of an Isolated Modular Multilevel DC-DC Converter
This study experimentally quantifies asymmetric losses in an Isolated Modular Multilevel DC-DC Converter (IM2DC) submodule, showing that low-side devices can dissipate up to twice the losses of high-side devices. A thermal imaging-based calorimetric method provides accurate, nonintrusive measurements, supporting future optimization of converter design, thermal management, and reliability.
