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 speed switching and, thus, low switching losses at the required high load currents, with only a comparatively low increase in conduction losses.
