Series-Connected Multi-Half-Bridge Modules Active Front-End Rectifier for Medium Voltage Variable Speed Drives
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Medium-Voltage Variable Speed Drives (VSDs) are the backbone of several critical industries. Providing the proper dc-link voltage to support the VSD's converter is crucial. Conventionally, dc-link voltage is supplied either ...
Exploitation of additional degrees of freedom of multiphase drives in low-frequency operation of modular multilevel converters
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
MMC encounters serious limitations in the zero and low-frequency operation of variable-speed motor drives. In MMC, the voltage ripples of SubModule (SM) capacitor is inversely proportional to the phase current frequency. ...
An H-Bridge Modular DC-DC Converter with Bidirectional Flyback-Based Energy Equalization Modules
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Conventional Modular Multilevel Converter (MMC) is a promising candidate in high-voltage high-power applications. Unfortunately, operating the conventional MMC with DC output voltage results in unbalanced capacitors' ...
