AGING INVESTIGATION OF INVERTER-FED LOW VOLTAGE MOTOR WINDING INSULATION SUBJECTED TO HIGH DV/DT

Résumé

The relevance of this paper determines by oncoming implementation of wide bandgap power semiconductors as SiC in inverters feeding motors. Hence, it is indispensable to investigate the influence of intensified electric stresses on winding insulation. In this regard, comparative corona resistance tests on pulse voltage with µs-and ns-level of rise/fall time were carried out. A novel specimen form for rectangular section wires is proposed. Considerations related to aging of dielectrics subjected to high dV/dt and high frequency pulse voltage are introduced.
