The results indicate that diamond components are not only viable but also that they might become alternatives to traditional materials used in power electronics. With their exceptional thermal dependent behavior and electrical properties, diamond diodes will play a crucial role in the future landscape of power electronics. This study confirms the potential of diamond-based components to revolutionize the industry, offering a glimpse towards the future of power electronics.

Accurate junction temperature estimation is a key requirement for ensuring reliability in power electronic systems, particularly under varying and constrained cooling conditions. In this work, we propose a multi-level thermal modeling strategy that combines physics-based and data-driven approaches to address the limitations of traditional models. A Foster-type RC network is first constructed using FEM simulations to capture self-heating and thermal coupling effects, then extended into a hybrid structure by incorporating experimental baseplate temperature measurements. To overcome sensor accessibility constraints and improve generalization, we further develop a MISO ARX model trained using on-board thermocouple data and hybrid model outputs as reference. The proposed methodology enables robust temperature prediction across different operating and cooling scenarios, requiring direct baseplate temperature measurements only during early laboratory tests, offering a practical solution for embedded systems where direct junction access is not feasible.

The growing need to decarbonize the transport sector has accelerated the development of sustainable alternatives to fossil fuels such as hydrogen-powered electric vehicles. In this context, power electronics converters are essential for efficient energy transfer and power flow management of Fuel Cell systems. This paper presents an innovative DC/DC converter architecture, referred to as the "Parallel-Cascade", that addresses the modularity and scalability demands of Multi-Stack Fuel Cell systems in Heavy-Duty applications. The proposed converter architecture is compared to conventional Multi-Stack configurations, using key performance indicators such as power losses, components stress factors, stored energy, and relevant qualitative criteria. Simulation results are provided under both normal and faulty operating conditions, highlighting the reconfiguration capability of the proposed control scheme. Prototype design and preliminary experimental validation are also presented.

The position angle is very important in the control loop of electrical machines. Position error presence has an influence on the current control precision and on the efficiency of the system. This paper presents a PLL based position estimation and angle compensation method. A comprehension study of the inverter acquisition and interruption system and their effects on sensorless control is also presented. This study concerns machines operating through a wide speed range which makes them more sensitive to acquisition filters. It is dedicated to electrification applications in automotive field where robust control is needed to maintain the stability of the system. It is applied to the control of a Permanent Magnet Synchronous Machine operating from 5 krpm to 185 krpm. Simulations and experiments are presented to validate the proposed study.
