Motor Overvoltage and Power Losses Analysis in Industrial Drives Based on Si and SiC Devices

Research activity was funded by Fidia spa
Pros and cons experimental assessment of three-phase inverter based on SiC devices
A converter with three-phase inverters (600 V x 30 A) compatible with all-Si, Si-SiC and all-SiC has been realized
Detailed efficiency analysis and comparisons of converter losses have been conducted
Investigation and modeling of the motor overvoltage problems caused by SiC devices
Study of filtering solutions for motor overvoltage mitigation
