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 ...
Quasi two-level PWM operation of a nine-arm modular multilevel converter for six-phase medium-voltage motor drives
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
This paper proposes a hybrid converter for medium-voltage six-phase machine drive systems that mixes the operation of a traditional two-level voltage-source inverter and the modular multilevel converter (MMC) to enable ...
A Modular Multilevel Converter with Integrated Shared Capacitor Sub-Module for MV Motor Drives Incorporating Symmetrical Six-Phase Machines
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
This paper proposes a new modular multilevel converter (MMC) configuration as a medium-voltage drive for variable-speed applications incorporating symmetrical six-phase machines. The proposed topology employs six MMC ...
