Open End Winding Synchronous Reluctance Motor Drive with GaN Multilevel Power Converters Energy Efficiency


This R&D project develops a bidirectional multilevel switching power converter using wide-bandgap semiconductors, as the Gallium Nitride (GaN) transistors to be applied in synchronous reluctance machines (SynRM) in open-winding configuration. The main goal is to obtain high energy efficiency motor drive system with high performance and reliability based on this configuration.

Subject Areas: wide-bandgap power electronic converters; open-winding synchronous reluctance machine
