Electric Potential Distribution in Three-Phase Windings under Pulse Voltage Stress

This research presents a novel method for predicting the potential distribution in electrical machines with random-wound windings under pulse voltage stress. A non-uniform potential distribution is caused by several factors including the introduction of fast-switching power semiconductors, continued improvements in power module design, the need for higher efficiency, and the integration and downsizing of components in new fields of application, such as electric vehicles and all-electric aircrafts.
