Resonant converters for electric equipment power supply
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014The paper deals with the use of resonant converters for the power supply of electric equipment. After exploring the advantages of using the resonant conversion, an analysis of the three main resonant topologies, namely i) series-resonant, ii) parallel-resonant, and iii) a combination of them, is carried out and a series resonant converter is ...

TUNNELS - ELECTRIC POWER SUPPLY.
Proceedings of the Institution of Civil Engineers - Civil Engineering, 1994This paper describes the electrical power supplies which were installed for the construction of the French section of the Channel Tunnel. Almost all the power consumed by the Channel Tunnel project (98%) was electrical. For an installed capacity of 85,000 kW, consumption was that of a town of 25,000 inhabitants.

Aircraft electric power-supply system
Electrical Engineering, 1943An ever increasing demand for electric power in aircraft has been felt for some time. The necessity of using an electric storage battery started the practice of accompanying it with a d-c generator, first of low current and voltage capacity, later of 50-ampere 12-volt rating, and for the past few years of 200-ampere 24-volt output.

Power quality and the security of electricity supply
Proceedings of the IEEE, 2001The high-tech and knowledge-oriented businesses of the 21st Century require high quality and ultra-reliable power in the quantities and time-frames which have not been experienced before. For mission-critical information systems, the availability of enhanced electric power is a far more important consideration than the commodity cost of electricity ...

Electric power quality and efficiency of power supply
21st IEEE Convention of the Electrical and Electronic Engineers in Israel. Proceedings (Cat. No.00EX377), 2002The quality of power supply depends on the quality of electrical energy, and also on the frequency and duration of probable interruptions in power supply, which increase with decrease of electric power quality (EPQ). The problem of EPQ has an important economic and technical significance for all countries, including Israel.

Emergency electric power supplies
Electronics and Power, 1964The continuing possibility of interruptions in the mains supply of electricity, particularly during very cold weather, emphasises the need for standby supplies for hospitals, mines, centres of communication and other services. The numerous methods of emergency generation and their applications are reviewed in this article.

Electrical Precipitation and its Power Supply
EUROCON 2005 - The International Conference on "Computer as a Tool", 2005This paper deals with a possibility of central energy supply instead of single supply of electrostatic filter cells designated for cleaning of the air in the street tunnels. It was observed the influence of an electric discharge between high voltage metal electrodes of the air electrostatic filter cell in connection with operating voltage of other ...
