Multi-Frequency Control of Single-Stage Converters using High-Frequency Isolation Transformers
DownloadFall 2021
Galvanic isolation using transformers is an important feature of many power converters, providing additional safety by separating the ground potential of two or more sections of an electrical system. High-frequency (HF) transformers increase the power density of converters by reducing the core...

This thesis proposes a multiport dc-dc modular multilevel converter, which is the first truly modular solution for a \"dc hub\" that can interconnect multiple MVDC or HVDC systems in future dc grids. The proposed converter, termed MP-DCMMC, consists of modular subconverters that can be added to...
