A Real-time Physics Based Digital Twin for Online MOSFET Condition Monitoring in PV Converter Applications Interuniversity Microelectronics Centre KU Leuven Hasselt University
This article proposes a fast, lightweight and physics-based digital twin to estimate the real-time junction, case and heat sink temperatures of the switching device in a photovoltaic (PV) boost converter. A lookup table approach is used to model the electric behavior while a traditional Cauer approach is used for the thermal model. To extract the thermal resistances of the MOSFET layers and convection, a finite element method (FEM) simulation is ...
