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. ...
Nine-phase six-terminal pole-amplitude modulated induction motor for electric vehicle applications
(
Institution of Engineering and Technology
, 2019 , Article)
In electric drive applications that are based on high-speed induction motors (IMs) with an extended speed range, stator winding pole-changing is a possible technique to avoid oversizing the driving motor. The electronic ...
Low-order space harmonic modeling of asymmetrical six-phase induction machines
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Multiphase machines are commonly analyzed using vector space decomposition modeling technique, where the original phase variables are decomposed into multiple orthogonal subspaces. The machine torque production and, ...
Carrier-Based PWM Strategy for Quasi-Z Source Nine-Switch Inverters
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Nine-switch Inverters (NSIs) have been proposed to accommodate the independent control of dual AC motors or in six-phase drives. This topology reduces the number of active switches by 25% compared with conventional Voltage ...
Zero-/Low-Speed Operation of Multiphase Drive Systems With Modular Multilevel Converters
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Modular multilevel converter (MMC)-based AC motor drives are emerging trend-research. They ease medium-/high-voltage handling in high-power applications with reduced footprint and life-cycle costs. A known challenge ...
HVDC shunt tap based on three single-phase half-bridge series-connected MMCs operated under 2L modulation
(
Institution of Engineering and Technology
, 2019 , Article)
In this study, a cost-effective HVDC shunt tap with low-number of relatively low-voltage semiconductor devices and small-sized passive components is proposed. The proposed architecture is based on employing three single-phase ...
A bidirectional non-isolated hybrid modular DC-DC converter with zero-voltage switching
(
Elsevier Ltd
, 2019 , Article)
In this paper, a bidirectional non-isolated hybrid modular DC-DC converter for high-voltage (HV) applications is investigated. In this configuration, conventional Half-Bridge Sub-Modules (HB-SMs) are employed. The proposed ...
