A DC autotransformer design for medium and high voltage DC transmission systems
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)This paper studies a dc-dc converter topology dual to the ac autotransformer for medium and high voltage dc-dc conversion. Operation with trapezoidal modulation is analyzed where the dc autotransformer is built of ... -
Hybrid and modular multilevel converter designs for isolated HVDC-DC converters
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Article)Efficient medium and high-voltage dc-dc conversion is critical for future dc grids. This paper proposes a hybrid multilevel dc-ac converter structure that is used as the kernel of dc-dc conversion systems. Operation of the ...
