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 ... -
Brushless doubly fed induction machine as a variable frequency transformer
( IEEE , 2012 , Conference Paper)Variable frequency transformer (VFT) has been recently used as an alternative to HVDC to control power flow between asynchronous networks. VFT consumes less reactive power than a back-to-back HVDC system, provides faster ... -
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 ... -
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 ... -
