Pengetesan Driver inverter | Osilator inverter
This work investigates the efficiency benefits of replacing Si power modules of automotive traction inverter applications with SiC-based power modules, for mission profiles such as the WLTP, NEDC and Artemis, at different boundary conditions such as switching speed, operating voltage, current, switching frequency and coolant temperature.
The compared power modules are in an identical package with state-of-the-art stray inductance optimized for fast switching, and only the chip technologies are varied. The rest of the system is kept the same too. This gives a direct comparison of Si versus SiC without giving scope for any discrepancies arising due to differences in the package, or due to differences in the system.
It is shown that SiC devices can bring upto 80% reduction in the inverter average power losses, which could pave the way for more efficient traction inverters.
