Effect of stator winding connection of five-phase induction machines on torque ripples under open line condition
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
One of the main challenges in designing high-power drive systems is the quality of the developed torque. High-torque-ripple magnitudes result in serious vibration and acoustic noise problems that affect the lifetime of a ...
An improved performance direct-drive permanent magnet wind generator using a novel single-layer winding layout
(
IEEE
, 2013 , Article)
Direct-drive permanent magnet (PM) generators have become a strong contender in medium and large rating wind energy conversion systems as they not only provide higher efficiency and annual energy production, but also reduce ...

(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
The modular multilevel converter (MMC) is a promising candidate for high-/medium-voltage high-power applications such as medium voltage ac drives due to its modularity, reliability, and scalability. The main challenge of ...
A HVDC shunt tap based on unidirectional hybrid modular DC-DC converter with simultaneous charging and sequential discharging of capacitors
(
Elsevier Ltd
, 2018 , Article)
In this paper, a new HVDC shunt tap is proposed. The proposed configuration consists of a unidirectional hybrid modular DC-DC converter followed by a voltage source converter for DC-AC conversion to feed a local AC network ...
A Grid-Connected Capacitor-Tapped Multimodule Converter for HVDC Applications: Operational Concept and Control
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
In this paper, a dc-ac buck converter is proposed as a grid-side converter in high voltage dc (HVdc) transmission systems for high-power renewable energy source grid integration. The proposed architecture consists of ...
Self-balanced non-isolated hybrid modular DC-DC converter for medium-voltage DC grids
(
Institution of Engineering and Technology
, 2018 , Article)
Here, a new bi-directional hybrid modular non-isolated DC-DC converter is proposed where it consists of a boost converter (BC) fed from the high-voltage (HV) side. At the BC output stage, a certain number of half bridge ...
