Abstract: The voltage stress of inverter-fed electrical machines increases when fast-switching wide-bandgap semiconductors are used. For the design of reliable electrical machines, it is therefore ...

Abstract: High frequency switching in an inverter fed AC electrical machine can cause high frequency circulating bearing currents which flow through a zigzag path in the stator laminations due to skin ...
