Design Trade-Offs of Modular Multilevel Converter-Based Arbitrary Wave Shape Generator for Conventional and Unconventional High Voltage Testing

This paper comprehensivelyinvestigates the design trade-offs of a Modular Multilevel Converter (MMC) operations as an Arbitrary Wave shapesGenerator (AWG) to perform High Voltage (HV) dielectric testing of different grid assets. HV AWG applications pose unique operatingconditions to the MMC, which i...
