Technical and economical evaluation on the use of reconfiguration systems in some EU countries for PV plants

2017

This paper shows the technical and economical evaluation of the application of a reconfiguration system for photovoltaic (PV) plants, considering the incentives system in some European Union countries. The reconfiguration system is an alternative to the distributed maximum power point tracking technique which used to increase the power production in the PV plants under the mismatch phenomenon. The reconfiguration techniques employ a microprocessor-based or field-programmable gate array-based system that modifies the layout of the PV plant through the change of the connections among modules. After having presented the main features working of the PV reconfiguration system allowing the improv…

Analysis of compressor architectures in MOS current-mode logic

2010

This paper is concerned with the design and the comparison of different compressor architectures for high performance multipliers in MOS current-mode logic (MCML). More specifically, three architectures have been designed for 3-2, 4-2 and 5-2 compressors and two architectures for 7-2 compressors. The various implementations for each type of compressor have been compared one another. This investigation indicates that the architectures based exclusively on three-level MCML gates are the most suitable for MCML implementation in terms of speed, power consumption and area. Design guidelines are provided to improve compressor performance. All the compressors were designed in a TSMC 180nm CMOS tec…

An FPGA-Based Software Defined Radio Platform for the 2.4GHz ISM Band

2006

A prototype of a Software Defined Radio (SDR) platform has been successfully designed and tested implementing a reconfigurable IEEE 802.11 and ZigBee receiver. The system exploits the reconfiguration capability of an FPGA for implementing a number of receiver configurations that share the same RF front-end. Configurations can be switched at run time, or can share the available logic and radio resource.

Automated Calculation Method to Determine the Output Power Based on the Frequency for Induction Heating IGBT Parallel Inverter

2007

The fact that some inverter topologies used in induction heating applications allow the soft switching working operation lets the progressive replacement of the MOSFET with the IGBT in high power inverters. This is due to two main reasons, the former is the IGBT reliability and the latter is the ratio defined as the price of the component per output power. In this article an automated method to determine the output power based on the frequency of an inverter build with different IGBT is described. To carry out this method is necessary to define the power cycle and to develop the calculation process which determines the energy losses in the working conditions of the resonant parallel inverte…

Heavy ion SEE test of 2 Gbit DDR3 SDRAM

2011

New generation 2 Gbit DDR3 SDRAMs from Micron, Samsung and Nanya have been tested under heavy ions. SEFIs significantly outweigh random SEU errors even at low LET; however, SEFIs can be mitigated by frequent re-initialization.

<title>Architecture for real-time wood inspection</title>

2000

This study has been realized to improve industrial machines that allow to analyze planks by detecting their width and too important defects thanks to a computer vision system. These machines are currently piloted by software with the help of PCs. The aim of our work is to realize a hardware card to increase the processing speed.

Compact instrumentation for radiation tolerance test of flash memories in space environment

2010

Aim of this work is the description of a test equipment, designed to be integrated on board of a microsatellite, able to investigate the radiation tolerance of non-volatile memory arrays in a real flight experiment. An FPGA-based design was adopted to preserve a high flexibility degree. Besides standard Program/Read/Erase functions, additional features such as failure data screening and latch-up protection have been implemented. The instrument development phase generated, as a by-product, a non-rad-hard version of the instrument that allowed performing in-situ experiments using 60Co and 10 MeV Boron irradiation facilities on Ground. Preliminary measurement results are reported to show the i…

Design and testing of the high speed signal densely populated ATLAS calorimeter trigger board dedicate to jet identification

2017

Abstract—The ATLAS experiment has planned a major upgrade in view of the enhanced luminosity of the beam delivered by the Large Hadron Collider (LHC) in 2021. As part of this, the trigger at Level-1 based on calorimeter data will be upgraded to exploit fine-granularity readout using a new system of Feature Extractors (three in total), which each uses different physics objects for the trigger selection. The contribution focusses on the jet Feature EXtractor (jFEX) prototype. Up to a data volume of 2 TB/s has to be processed to provide jet identification (including large area jets) and measurements of global variables within few hundred nanoseconds latency budget. Such requirements translate …

Development of an optical link card for the upgrade phase II of TileCal experiment

2010

This work presents the design of an optical link card developed in the frame of the R&D activities for the phase 2 upgrade of the TileCal experiment as part of the evaluation of different technologies for the final choice in the next two years. The board is designed as a mezzanine which can work independently or plugged in the Optical Multiplexer Board of the TileCal backend electronics. It includes two SNAP 12 optical connectors able to transmit and receive up to 75 Gbps and one SFP optical connector for lower speeds and compatibility with existing hardware as the Read Out Driver. All processing is done in a Stratix II GX FPGA. Details are given on the hardware design including signal and …
