The performance in magnetic field (B-field) of a DC-DC converter ad hoc designed for LHC operation has been evaluated. The tests have been carried out at the Laboratorio Acceleratori e Superconduttività Applicata (LASA), in Milan (Italy), in the first months of 2014 and the experimental results are here presented and discussed. The ability to operate in hostile environment of the tested DC-DC converter...
Devices used in future experiments at LHC will be called to work in a very hostile environment. Power supply is a key aspect in this scenario, and new converters will be re-designed in order to meet the future requirements. Moreover, also Point of Load (PoL) converters, as circuits able to adapt the voltage level for each board, device and situation, need to be re-designed in order to meet the future...
The reliability of a power converter can be improved using a well-dimensioned cold plate. At this aim it is necessary to realize a state of the art cold plate by means of thermal-fluid dynamic numerical analysis and ad-hoc designed experimental test bench. Features and metrological characterization of test bench for cold plate design and verification will be discussed in this paper.
Devices used in future experiments at LHC will be called to work in very hostile environment. Power supply is a key aspects in this scenario and new converter will be re-designed in order to meet the future requirements. In this paper a main DC-DC power converter, developed by authors in the framework of the APOLLO R&D project, has been proposed and the experimental activity devoted to its characterization...
In modern industrial applications, because of the increasing requirements in term of quality and efficiency, the employment of an effective maintenance strategy is becoming crucial. As a consequence, the service activity is moving towards the development of diagnostics and prognostics techniques aiming to minimize the impact of the failures on the production. In previous papers two simple diagnostic...
In this paper, a novel virtual-instrument-based monitoring and diagnosis technique that permits the identification of rotor faults in small inverter-fed induction motors is presented and discussed. Since it allows the continuous monitoring of the machine, it is a useful tool for the implementation of advanced maintenance strategies. Through a proper experimental setup, the performance, repeatability,...
