Aros Solar Technology - L'energia dell'innovazione



Fin dalla nascita, nel 1935, il cammino di AROS si riconosce in un percorso perfettamente lineare: mettere l'eccellenza tecnologica al servizio degli impianti elettrici. Per decenni, AROS è leader riconosciuto nel settore dei gruppi statici di continuità. Il 2006 vede il debutto dell'azienda nell'ambito delle energie rinnovabili con l'introduzione di una prima gamma di inverter, oggi ampliata con modelli da 1,5kW a 500kW e da complete soluzioni di monitoraggio. L'offerta AROS è in grado di coprire ormai ogni esigenza, dal piccolo impianto domestico alle centrali solari. Il core business del gruppo sono le imprese che operano nell'area della conversione dell'energia e nella produzione dei gruppi elettronici di continuità.

Latin America’s Surging Three-Phase UPS Market Projected to Reach $330 Million by 2015

Date: 23 November 2011

Uninterruptible Power Supply (UPS) revenues grew 24% in 2010, with a spectacular 58% surge for three-phase UPS greater than 100 kVA, according to a recent study on the market from IMS Research. In 2010, high power three-phase UPS, which are typically associated with data centers, picked up nearly 3 points share of Latin America’s UPS market thanks to the staggering growth in Brazil and Mexico. Latin America’s three-phase growth is forecast to continue with the help of government and infrastructure investments particularly in Brazil and Mexico.

Much of Latin America’s growth in 2010 can be attributed to the expanding IT market. The three-phase segment is forecast to continue seeing substantial gains as capital spending is going towards data center projects across all industries. Furthermore, single-phase UPS growth is slowing as compared to three-phase UPS growth since voltage regulators and laptop computers, which eliminate the need for an UPS, are becoming more widely used in Latin America.

“Brazil presents the best opportunity for three-phase UPS growth” says IMS Research Market Analyst Lori Lewis. “With an economically healthier middle class, more individuals are able to take advantage of modern day information technology and mobile computing devices resulting in exponentially growing computing and data storage needs. Three-phase UPS going into data centers will have to grow just as fast in order to keep up with all of this increased demand.”

Mexico is also experiencing a lot of activity, with large data center builds going into medium and large businesses, banking and infrastructure advances. Mexico, in fact, boasts significant advantages for foreign investors over Brazil due to fewer import taxes, fewer local competitors, fewer barriers to entry into the market and an overall more sustainable growth. Columbia has come under the radar as a promising investment with a well-educated population. The corruption, guerilla warfare and drug trafficking that scared investors away in the past has slowly subsided, allowing the country to develop properly.

With a good mix of established and fast-growing developing economies, Latin America is seen as secure and profitable for UPS suppliers looking to enter the market or enhance their presence in the region. Since Schneider Electric’s acquisition of local manufacturer Microsol, and Legrand’s recent acquisition of the large single-phase supplier SMS Technologia, the region continues to pick up global attention and stirs up the question of who will be next.

Abstract:
The future smart electric grid needs not only smart meters but also smart transmission and distribution technologies. Power electronics will play an important role in the future smart transmission by enhancing the transmission capacity, reliability, and security. Currently, transmission systems are becoming increasingly stressed because of growing demand and because of restrictions on building new lines. However, most high voltage transmission systems are operating below their thermal ratings due to such constraints as stability limits.

Despite the enormous potential of solar power to generate electricity, solar photovoltaic (PV) technology is by far the least utilized renewable energy resource today. We need breakthrough advances in materials to capture and store solar energy so we can economically replace fossil fuels in the next few decades. Prof. Grossman will describe two radically new solar materials and the computational models that led to their discovery.

CEM 2011 - Review of Eddy current analysis


Prof Oszkar Biro


This conference provides a forum for the presentation and discussion of research into computational techniques for solving problems in electromagnetics, with focus on aspects and applications of numerical modelling based on these techniques. Both low and high frequency fields will be covered, as well as electromagnetic hazards and EMC.

The conference will provide an opportunity for experts in the field, including practising engineers and designers, to meet and exchange information on recent developments in electromagnetic modelling. It will be of interest to academics undertaking research in electromagnetics and to engineers in fields such as telecommunications, propagation and remote sensing, power, defence and transport, where the electromagnetic aspects are crucial.

The focus is on an inclusive conference with networking opportunities. The emphasis is on interactive (poster) presentations with plenty of opportunities for informal discussions. Each session will start with invited oral introductory reviews of the relevant topics.
