Open loop V/f control of multiphase induction machine under open-circuit phase faults
(
IEEE
, 2013 , Conference Paper)
One of the main advantages of multiphase induction machines is their higher fault-tolerant capability. Under phase(s) loss, the machine currents can be optimally controlled to satisfy certain optimization criteria. In this ...
A modified modulation scheme for capacitor voltage control of renewable energy-fed grid-connected Z-Source Inverters
(
IEEE
, 2012 , Conference Paper)
An important issue in grid connection applications is boosting the limited output voltage of the renewable energy sources. Two-stage converters are most commonly employed for successful grid connection and optimum power ...
Single sensor three-phase permanent magnet synchronous motor drive based on Luenberger style-observers
(
IEEE
, 2012 , Conference Paper)
This paper presents a technique to estimate phase currents and rotor position in a vector-controlled PMSM drive using only dc-link current measurement. Three cascaded Luenberger style observers were used to perform this ...
A single-stage three-phase DC/AC inverter based on Cuk converter for PV application
(
IEEE
, 2013 , Conference Paper)
This paper presents a new three-phase dc-ac inverter based on the basic Cuk converter. The main feature of the proposed topology is the fact that the energy storage elements as inductors and capacitors values can be reduced ...
Magnetic gearbox with an electric power output port and fixed speed ratio for wind energy applications
(
IEEE
, 2012 , Conference Paper)
Mechanical gearboxes are typically employed with doubly-fed induction generator-based wind turbines. The main drawback of this solution is the gearbox's reliability and maintenance. Using magnetic gearbox in conjunction ...
A coaxial magnetic gearbox with magnetic levitation capabilities
(
IEEEIEEE
, 2012 , Conference Paper)
Magnetic gearboxes (MGBs) are now a powerful alternative to their conventional mechanical counterparts in terms of reduced maintenance requirements, improved reliability, tolerance to mechanical inaccuracies, and inherent ...
Control of doubly-fed induction machine storage system for constant charging/discharging grid power using artificial neural network
(
IET
, 2012 , Conference Paper)
A large-capacity low-speed flywheel energy storage system based on a doubly-fed induction machine (DFIM) basically consists of a wound-rotor induction machine, and a back-to-back converter for rotor excitation. It has been ...
A power control strategy for flywheel doubly-fed induction machine storage system using artificial neural network
(
Elsevier Ltd
, 2013 , Article)
A large-capacity low-speed flywheel energy storage system (FESS) based on a doubly-fed induction machine (DFIM) consists of a wound-rotor induction machine and a back-to-back converter rated at 30-35% of the machine power ...
Traction system with on-board inductive power transfer
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
In traction applications based on long primary and short secondary type, contactless electrical energy transmission can offer distinct advantages over the conventional energy transmission based on catenary system to provide ...
