Low Loss High-Power Thyristors for Industrial Applications

Posted on 19 November 2015

      Though one of the oldest semiconductor devices ever, the thyristor maintains a significant market share. This is because of its attractive price-performance ratio mainly due to the lowest ON-state losses and the easiest processing from existing gated switches. ABB has developed a new range of thyristors offering very low ON-state voltage drop, [...]

How Proper Applications of Thermally Conductive Materials will Improve Motor Power Density

Posted on 30 July 2015

      Motor designers have battled heat in motor designs for years. Thermal losses in electric machines rob motion systems of power and degrade efficiency. Excess heat can reduce reliability of motors and shorten their lifetimes. Meanwhile, electrification in all transportation sectors is driving requirements for motors with ever-higher power densities. By Anita LaFond, [...]
