   Analysing DBD Plasma Lamp Intensity versus Power Consumption Using a Push-Pull Pulsed Power Supply
By Pooya DAVARI, Firuz ZARE, Arindam GHOSH [View]
[Download]

Abstract: In this paper characteristic of a DBD (Dielectric Barrier Discharge) plasma lamp is investigated basedon the lamp intensity and power consumption. A pulsed power supply with controllable parametersbased on a push-pull converter is developed for lamp excitation at different voltage levels andrepetition rate. The experimentations were conducted for 28 different operating points with thefrequency range of 2 kHz to 15 kHz at output voltage levels of between 7.4 kVpp up to 13 kVpp. Theobtained results show the feasibility of finding an optimum operation point due to nonlinear behaviourof the DBD lamp.

   Power System Design Compromises for Large-scale Linear Particle Accelerators
By Konstantinos PAPASTERGIOU, Davide AGUGLIA [View]
[Download]

Abstract: This paper discusses various design aspects of a 280MW Power System for the Compact Linear Collider (CLIC), a 50km long electrons-positrons accelerator, under feasibility evaluation. The key requirements are a very high accelerator availability and constant power flow from the utility grid, considering the pulsed power nature of CLIC. Firstly, the possible power network and cabling layouts are discussed along with potential difficulties on electrical fault clearance. Following, the use of active front-end converters is examined as a means to control the power flow and power quality seen by the 400kV grid. In particular a modular multilevel converter preliminary configuration is described and the compromises related to energy storage and voltage level are discussed.

   Pulse Transformer Design for Magnet Powering in Particle Accelerators
By Davide AGUGLIA [View]
[Download]

Abstract: This paper presents an optimal design procedure for pulse transformers fed by power converters forsupplying pulsed current magnets in particle accelerators. Usually their volume must be minimizedbecause of limited space available in the accelerator tunnel. Analytical and numerical models arepresented as well as an experimental validation and a real case study where the design tool isexploited to derive a wide variety of solutions depending on the pulse transformers location withrespect to the magnet position.
