Power electronics - a specific area of knowledge engineering, where a lot is determined not so much a purely theoretical knowledge as experience, erudition, lively search for ways to design reliable electronic equipment. Ways of solving a technical problem of power electronics can be quite unconventional, although there are a number of rules, without observing that if nothing is impossible to develop workable.
This book is designed to help get involved in the design, construction and operation of static converters of electricity on the basis of modern semiconductor power components. The book is addressed to engineers and technicians engaged in the development, modernization and repair of power electronics, and students of higher secondary schools, as well as anyone interested in the problems of converters.

Chang Zheng 3B Night Launch with NIGCOMSAT-1R satellite Cohete chino CZ lanza el satélite nigeriano NigComSat-1R
December 19, 2011 - Xichang Satellite Launch Center.
China successfully sent a Nigerian communication satellite into orbit with its Long March-3B carrier rocket from southwest Xichang Satellite Launch Center at 00:41 Beijing Time Tuesday.
The satellite, produced by China Academy of Space Technology, will provide communication, broadcast, Internet connection, remote education and navigation services to parts of Africa, Europe and Asia.
China will also provide monitoring and control services for the satellite and support its ground stations.
It was the third time China provided satellite launch service for foreign users this year, following the successful launch of two Pakistani communication satellites.
China plans to launch four to five satellites for foreign users in 2012.
Cohete chino CZ lanza el satélite nigeriano NigComSat-1R
Un cohete chino Larga Marcha-3B/E (Chang Zheng-3B / E) lanzado desde el Centro Espacial de Xichang puso en órbita el satélite nigeriano NigComSat-1R.El NigComSat-1R (Nigeria Communication Satellite) es un satélite de comunicaciones geoestacionario de 5.150 kg construido por CAST (China Academy of Space Technology) subsidiaria de la Corporación China de Ciencia y Tecnología Aeroespacial (CASC), para la empresa NigComSat Ltd de Nigeria una compañía estatal responsable de la operación y gestión de los satélites de comunicaciones nigerianos.
Este satélite fue encargado llave en mano en marzo de 2009 a China Great Wall Industry Corporation (CGWIC) que actúa como contratista principal del programa.

ABB to acquire Newave to broaden offering in uninterruptible power supply
ABB announces all-cash public tender offer of CHF 56 per Newave share, representing a total equity value of approximately CHF 170 million, to be unconditionally recommended by Newave’s Committee of independent members of the Board of Directors
Offer price represents a premium of 36.0% to the volume-weighted average share price of the last 60 trading days and a premium of 22.4% to the closing price on December 9, 2011
The three major shareholders of Newave, representing in total 45% of the voting rights and share capital, have signed separate agreements to sell their shares under the same financial conditions as offered in the public tender offer
ABB plans to develop Newave to become a center of excellence for UPS systems
Zurich and Quartino, Dec. 12, 2011 – ABB (ABBN.VX), the leading power and automation technology group, and Newave Energy Holding SA (NWEN.S), a Switzerland based leader in uninterruptible power supply (UPS), have agreed that ABB will acquire Newave in an all-cash transaction valued at approximately CHF 170 million1. The deal will strengthen ABB’s position in the power control and quality market and provide Newave with significant growth opportunities outside its traditional markets in Europe.
1 Fully diluted equity value
Under the terms of the transaction agreement, ABB today announced a voluntary all-cash public tender offer of CHF 56 per Newave share to purchase all of Newave’s publicly held shares. The offer prospectus will be published on or around Dec. 15. The offer represents a premium of 36.0 percent to the volume-weighted average share price of the last 60 trading days and a 22.4 percent premium to Newave’s closing stock price on Dec. 9. The Committee of independent members of the Board of Directors of Newave will unconditionally recommend that Newave shareholders tender their shares in the offer.
Under separate share purchase agreements, ABB acquires not conditional upon the public tender offer being successful a 45 percent stake in Newave held by the three major shareholders – being the two founders Vllaznim Xhiha, current Chairman of the Board of Directors, and Filippo Marbach, current Member of the Board of Directors and Chief Operating Officer, as well as Rittal International Stiftung & Co. KG. The major shareholders will receive the same consideration per Newave share as offered by ABB to public shareholders in the public tender offer.
Newave, headquartered in Quartino, Switzerland, generated a net income of CHF 8.1 Million on sales of CHF 80.6 Million in 2010. The company was founded in 1993 and went public in 2007. Newave has established a strong market position in Europe as an innovative and successful manufacturer of UPS systems with a focus on the development and production of power protection technology, as well as on technical consultancy, maintenance and service packages. ABB plans to integrate Newave in its Discrete Automation and Motion division and develop Quartino to become a main location for ABB’s UPS systems. ABB will provide a fast, global exposure for Newave’s UPS systems and will ensure that Newave can increase the high innovation rate of its current product range.
“The combination of two strong, complementary companies will create significant value-driven growth based on innovation, high quality and technology leadership,’’ said Ulrich Spiesshofer, head of ABB’s Discrete Automation and Motion division. “The acquisition is fully in line with ABB’s strategy for power control and quality and with the goal of the division to build on its existing strength in power electronics. Newave provides us a best-in-class player in the fast-growing UPS market, while our global sales channels will significantly expand Newave’s geographic reach.”
“Combining our business with ABB will give Newave important strategic and operational advantages. As Chairman of the Board of Directors of Newave, I am convinced that ABB is the ideal partner for the continuous successful development of our company,” said Newave’s Vllaznim Xhiha. “Besides the immediate financial added value of the offer for the shareholders, we also expect considerable additional development potential for Newave’s business partners and its employees.”
The global UPS market offers interesting growth opportunities, mainly in the areas of datacenters, industry and infrastructure. ABB will expand into a $6 billion to $7 billion market and close a white spot in core datacenter electrification and industrial power quality. Newave is active in the medium- and high-power UPS range, which is the most attractive segment since it represents 50 percent of the overall UPS market with a yearly growth rate of 6 to 10 percent. ABB has a strong presence in industrial markets and already offers industrial UPS products. It recently acquired a majority share in the DC datacenter solution provider Validus. Combining ABB’s and Newave’s market presence and technological expertise will allow ABB to offer a complete range of UPS solutions to industrial, commercial and datacenter clients with a comprehensive alternating current (AC) and direct current (DC) solutions portfolio, reinforcing its strategic differentiation.
Taking into consideration a fairness opinion by Bank Sarasin & Cie AG, the Committee of independent members of the Board of Directors of Newave – consisting of Rudolf Kägi and Mauro Saladini – regards the offer by ABB as fair and appropriate. The Committee will recommend to the shareholders of Newave to accept the offer in its report to be issued in ABB’s offer prospectus.
The public tender offer and the closing of the share purchase agreements are subject to regulatory approvals and other customary conditions. The offer period is expected to start in early January 2012 and the transaction to close in the first half of 2012.
