High Power Medium Voltage Converters Enabled by High Voltage SiC Power Devices

This paper presents the potential applications of HV SiC power devices for high power and medium voltage power conversion systems. The advantages and features enabled by HV SiC devices are experimentally validated by both device performance evaluations as well as operation and performance validations of MV power conversion systems. The potential application examples of Solid State Transformer (SST), Asynchronous Microgrid Power Conditioning Systems, MV motor drives, MV grid connected converters for integration of Distributed Renewable Energy Resources (DRER) and Distributed Energy Storage Devices (DESD) are presented as design case studies and experimental validations with their advantages and power conversion efficiency.
