Hardware Prototype for the Quasi-Two-Level Operation of a Three-Phase Flying Capacitor Converter for Medium Voltage Applications

Today's standard medium voltage converters are operated with low switching frequencies and contain bulky passive components. One concept to change this is the Quasi-Two-Level operation of a multilevel converter with SiC semiconductors. A three-phase hardware setup for a Quasi-Two-Level Flying C...

Summary:Today's standard medium voltage converters are operated with low switching frequencies and contain bulky passive components. One concept to change this is the Quasi-Two-Level operation of a multilevel converter with SiC semiconductors. A three-phase hardware setup for a Quasi-Two-Level Flying Capacitor Converter with control and measurement results in a test setup are presented.
