High Voltage SPT+ Diodes

Posted on 01 October 2019

      The Perfect Match The newly developed SPT+ diode technology platform for 3.3kV, 4.5kV and 6.5kV diodes for next generation high power IGBT modules is described in this article. The new diode range offers low losses and soft recovery characteristics combined with a high reverse recovery safe operating area and superior surge current [...]

The 4th Generation of the 1200V Emitter-Controlled Freewheeling Diode

Posted on 01 October 2019

       A Soft Alternative Freewheeling diodes are one of the important components for IGBT modules and have to satisfy a number of demands. Especially in hard switching applications, such as inverters for industrial drives or UPS, a soft switching behaviour of the diode as well as low losses and high ruggedness – is [...]

Advances in SiC Rectifiers

Posted on 01 October 2019

       SiC can eliminate the need for many other components One of the biggest advances in silicon carbide rectifier technology is the creation of better material in larger sizes. By moving from 3-inch wafers to 4-inch, suppliers have achieved greater manufacturing efficiency and are driving down the costs of SiC devices. By John [...]

The SmartRectifier in Practical Design

Posted on 01 September 2019

       A step forward for secondary-side rectification Power supply architecture has become a major issue in product design over recent years. At the core of this trend has been the decrease in digital IC voltages, while overall power densities have moved in the opposite direction. By Mario Battello, International Rectifier   Change has [...]
