Abstract: This document details the results of a cosmic ray radiation test performed on two planar SiC power MOSFET technologies belonging to the 650V and 1200V voltage classes. The testing followed JEDEC standard JEP151A, using a 200 MeV proton beam to simulate the effects of cosmic ray-induced single event burnout (SEB). The testing involved comprehensive […]

For designing highly efficient traction inverters for eTrucks a new 1400 V SiC MOSFET is being introduced. Due to high phase currents typical for eTRUCKs, even in low-inductive setups high switching-overvoltages occur that limit the switching speed of 1200 V devices, leading to largely increased switching losses. The new 1400 V SiC MOSFET enables high […]

This paper presents design requirements and solution strategies for power semiconductor modules targeting traction converters for electric trucks (eTRUCK). It is shown that, due to the needed high load, long distance mission profiles, robustness against cycling load, i.e., device lifetime, is the main differentiator to consider. For optimized efficiency and reduced module package size, a […]

Safety-critical functions must be highly available during automated driving. Therefore, a stable power supply is needed, even in the case of a fault within the supply system. To design such a fail-operational system, the effects of all possible fault scenarios must be investigated during the development process. For this, simulations can be beneficial. Critical scenarios […]

Highly automated driving places very high safety requirements on the reliability of the power supply in the vehicle. To meet these high requirements, new vehicle electrical system designs and redundancy concepts are being investigated. Replacing conventional melting fuses with electronic fuses can provide more voltage and current signals that can be used for the analysis […]
