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)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. ... -
Hybrid-boost modular multilevel converter-based medium-voltage multiphase induction motor drive for subsea applications
( Korean Institute of Power Electronics , 2019 , Article)This paper proposes a hybrid-boost Modular Multilevel Converter (MMC) for the Medium-Voltage (MV) Variable Speed Drives (VSDs) employed in subsea applications, such as oil and gas recovery. In the presented architecture, ... -
Sensor-less operation of hybrid boost modular multilevel converter for subsea multiphase medium voltage drives
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference)This paper introduces Hybrid Boost Modular Multilevel Converter (Hybrid Boost MMC) as a suitable candidate for subsea drive systems. The investigated drive system is based on a five-phase Induction Machine (IM) in order ... -
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)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 ...
