Design and Commissioning of a 10 kV Three-Phase Transformerless Inverter with 15 kV Silicon Carbide MOSFETs
Abstract
A medium voltage inverter based on 15 kV Silicon Carbide (SiC) MOSFETs is presented in this paper. By using a three-level topology it is possible to feed directly into a 10 kVAC distribution grid. Measurement results of the successful operation at full output voltage are shown. A maximum efficiency of over 97% is reached.
