A wind turbine architecture employing a new three port magnetic gear box
(
IEEE Computer Society
, 2012 , Conference Paper)
Mechanical gearboxes are typically employed with doubly-fed induction generator based wind turbines to convert the turbine's low speed mechanical power into high-speed mechanical power to drive the electrical generator. ...
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 ...
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 ...
