The Gulf Cooperation Council as a New Regional Power: Time for the EU to Propose a Strategic Partnership. Bruges Regional Integration & Global Governance Papers 3/2012, November 2012

The Gulf Cooperation Council (GCC) is a de facto regional power in the Arab world. Its role has been crucial in some of the outcomes of the Arab Spring. The GCC countries have been very pragmatic in dealing with the uprisings, avoiding any revolutionary spill-over throughout the Gulf region. This paper examines to what extent the policies of the European Union (EU) in the Gulf have changed since the beginning of the Arab Spring. It argues that despite the calls by the European Parliament and by the High Representative Baroness Ashton to improve the relationship, the EU’s support for a new policy in the Gulf after the Arab Spring is stalling, and little new or concrete has been achieved. The paper concludes that the Union needs a reinforced partnership that merges the various EU policies in the region into a single strategic partnership with the Arab countries.

Design, implementation and characterisation of a contactless power transfer system for rotating applications

This paper describes the design, implementation and characterisation of a contactless power transfer system for rotating applications. The power transfer system is based upon a zero-voltage-switched, full-bridge, DC-DC converter, but utilises a non-standard transformer. This transformer allows power transfer between its primary and secondary windings while also allowing free rotation between these windings. The aim of this research is to develop a solution that could replace mechanical slip-rings in certain applications where a non-contacting system would be advantageous. Based upon the design method presented in this paper, a 2 kW prototype system is constructed. Results obtained from testing the 2 kW prototype are presented and discussed. This discussion considers how the performance of the transformer varies with rotation and also the overall efficiency of the system

Contactless power transfer system for rotating applications

In applications such as radar and wind turbines, it is often necessary to transfer power across a constantly rotating interface. As the rotation is continuous, it would be impossible to use wires to transfer the power as they would soon become twisted and stretched and the system would fail. The widespread solution to this problem is to use a slip-ring.
