Abstract: For power conversion, a power conversion system includes a plurality of power converters and a phase shifting transformer. The phase shifting transformer includes 3-phase primary windings, a core and a plurality of m secondary winding groups. Each of the secondary winding groups includes n secondary windings in electromagnetic communication with a corresponding primary winding and feeding the plurality of power converters. Phase angle sets of the secondary winding groups are all different with a non-zero secondary winding phase shift between any two secondary winding groups.

Abstract: A system for detecting partial discharge in electrical components may include a control system that may operate a drive in an industrial automation system. The industrial automation system may include the electrical components being analyzed for partial discharge. The system may also include one or more acoustic sensors that may detect one or more acoustic waveforms generated within at least one of the electrical components. The system may also include a monitoring system that may receive the acoustic waveforms from the acoustic sensors and determine whether the one electrical component is experiencing partial discharge based on the acoustic waveforms. The monitoring system may then send a notification to the control system when the one electrical component is determined to be experiencing partial discharge, such that the notification indicates that the one electrical component is experiencing partial discharge.
