The history of ABB goes back to the late nineteenth century, and is a long and illustrious record of innovation and technological leadership in many industries. Having helped countries all over the world to build, develop and maintain their infrastructures, ABB has in recent years gone over from large-scale solutions to alternative energy and the advanced products and technologies in power and automation that constitute its Industrial IT offering.

ABB is a publicly listed company that operates in approximately 100 countries. We are headquartered in Zurich, Switzerland, and our shares are traded on the stock exchanges of Zurich, Stockholm and New York.
We manage our business based on a divisional structure. Our business comprises five divisions: Power Products, Power Systems, Discrete Automation and Motion, Low Voltage Products, and Process Automation. R&D fuels innovation at ABB
Investment in R&D was $1.3 billion in 2009, 4.1 percent of revenues: product launches include a new solar inverter, drives for water industry, rail converters, HVDC systems with higher capacity, a compact robot, moulded-case circuit breakers XT series, SACE Formula circuit breakers, a new generation of first-class specialized control and protection devices and the remote switch unit S800-RSU for solar applications (which has won the Intersolar AWARD 2010 at the world’s largest exhibition for the solar industry in Munich).
We have seven research centers, 6,000 researchers and developers, and 70 university collaborations across the world.
The ABB group currently manages around 4,780 active patent families and about 19,890 active patent applications.
Good leaders are characterized by competence, ambition and integrity
All three ensure that we create value by fulfilling our commitments to our customers, our employees and the communities and societies in which we operate, acting in accordance with sound corporate values.
To build value, performance and leadership into ABB, responsibility, respect and determination are key
Assuming responsibility, and acting with respect and determination makes it possible to nurture ABB’s traditional strengths – our technology leadership, our pioneering spirit and our ability to be at home everywhere. That is our legacy, and our future. The key to success lies in how well all of us understand and apply the business principles – demonstrating personal, professional and corporate responsibility, showing respect for the views and needs of others and applying our shared determination to win.
Through a series of workshops, ABB employees have helped to define what the business principles of responsibility, respect and determination mean
As one of the world’s leading engineering companies, we help our customers to use electrical power efficiently, to increase industrial productivity and to lower environmental impact in a sustainable way. Power and productivity for a better world
IGBT and Diode Dies
IGBT conduction losses are somewhat higher compared to GTOs and IGCTs. Turn-off losses, on the other hand, are lower. For this reason, the optimum IGBT switching frequency is higher with respect to GTOs and IGCTs of the same ratings. The IGBT can be applied without any protective networks ('snubbers'), thus enabling extremely simple system topologies. The price of this simplicity is that a larger portion of the system losses is dissipated in the ...
The first steps to superior quality in gravity casting are highly precise ladling and pouring processes. Once the ideal pouring curve has been identified, robots will stick to the procedure, bringing repeatability to the entire process. Perfectly cast parts require less finishing. Still the blasting grinding or waterjet cleaning of the cast part is indispensable and yet another area where robots can enhance efficiency and product quality in ...
