Towards the 2nd edition of IEC 60034-18-41: challenges and perspectives

This paper deals with the challenges and perspectives for the 2^nd edition of the IEC 60034-18-41. The stress imposed by wide bandgap inverters on the turn insulation will be discussed as well as the differences in the behavior of PDIV as a function of thermal aging when tested using 50/60 Hz AC voltage waveforms or SiC impulse voltages. Consideration for the application of this document to the field of traction electrification will also be discussed.
