A Modular Superconducting Generator for Offshore Wind Turbines
Keysan, Ozan; Mueller, Markus A (2013-05-01)
In this study, a new claw-pole type transverse flux superconducting generator topology is presented. The machine has a stationary superconducting field winding, which eliminates electrical brushes and cryocouplers. The machine is specifically designed for low-speed high torque applications such as large offshore wind turbines. The proposed machine is robust and has a modular structure.
A direct drive permanent magnet generator design for a tidal current turbine SeaGen
Keysan, Ozan; Markus, Mueller (2011-05-15)
In this study, the feasibility of a direct-drive permanent magnet generator for a tidal turbine power take-off system, namely MCT's SeaGen - the world's first full scale commercial tidal turbine- has been investigated. The investigated PM generator topology is called C-GEN which is an air-cored axial-flux generator developed in the University of Edinburgh. The C-GEN is prior to conventional PM generators by absence of magnetic attraction forces between rotor and stator, absence of cogging torque, ease of ma...
A modular and cost-effective superconducting generator design for offshore wind turbines
Keysan, Ozan (IOP Publishing, 2015-03-01)
Superconducting generators have the potential to reduce the tower head mass for large (similar to 10 MW) offshore wind turbines. However, a high temperature superconductor generator should be as reliable as conventional generators for successful entry into the market. Most of the proposed designs use the superconducting synchronous generator concept, which has a higher cost than conventional generators and suffers from reliability issues. In this paper, a novel claw pole type of superconducting machine is p...

ULUSAN, HASAN; CHAMANIAN, S.; PATHIRANA, W. P. M. R.; ZORLU, O.; MUHTAROGLU, A.; Külah, Haluk (IOP Publishing, 2018-01-01)
This study presents a triple hybrid energy harvesting system that combines harvested power from thermoelectric (TE), vibration-based electromagnetic (EM) and piezoelectric (PZT) harvesters into a single DC supply. A power management circuit is designed and implemented in 180 nm standard CMOS technology based on the distinct requirements of each harvester, and is terminated with a Schottky diode to avoid reverse current flow. The system topology hence supports simultaneous power generation and delivery from ...
A Transverse Flux High Temperature Superconducting Generator Topology for Large Direct Drive Wind Turbines
Keysan, Ozan (2012-01-01)
The cost and mass of an offshore wind turbine power-train can be reduced by using high-temperature superconducting generators, but for a successful commercial design the superconducting generator should be as reliable as its alternatives. In this paper, we present a novel transverse flux superconducting generator topology which is suitable for low-speed, high-torque applications. The generator is designed with a stationary superconducting field winding and a variable reluctance claw pole motor for simplifie...
