Our 100-year-old story makes compelling reading. Our advanced semiconductor technology has created almost unlimited control possibilities in HVDC transmission systems. The exceptional quality and design of our BiPolar and IGBT devices bring unparalleled reliability to the most demanding of applications. We lie at the heart of traction converters driving high speed trains, metros and diesel-electric locomotives. And the many pumps, fans, roller tables, hoist and winches found throughout industry, rely on us. We are ABB Power Grids – Semiconductors. With production in Lenzburg, Switzerland and Prague, Czech Republic and a new research laboratory in Baden-Dättwil, Switzerland, we are more than ready for the next 100+ years.
