Modeling and Analysis of Near-Field Radiated Emission in Wide Bandgap Power Modules

Recent advances in wide bandgap power devices have resulted in increasing power density for power converters. Near field models of power modules are essential to design better packaging of other auxiliary circuits in a power converter. A simplified power module like structure is considered. The entire power module is then subdivided into simpler geometries and modeled separately. The overall map of near field is then obtained from these simple geometries. The result from the simulation and measurement has been compared to the modeled map to validate the model.
