(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
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 ...
Model-predictive control for common-mode voltage reduction and third-harmonic current injection techniques with five-phase inverters
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
This paper employs a Model Predictive Control (MPC) technique to reduce the Common-Mode-Voltage (CMV) in five-phase inverters when third harmonic current injection is applied. According to the inverter space vector model, ...
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 ...
