Ensuring System Efficiency

Posted on 29 April 2015

      Four Key Features to look for in a GaN-Ready Magnetics Supplier The dramatic rise in the popularity of Galium Nitride (GaN) switching technology is due to the very significant benefits it provides. Highly efficient GaN devices offer high dielectric strength, high operating temperatures, high current density, high-speed switching and exceptional carrier mobility. [...]

Performance Comparisons of SiC Transistors, GaN Cascodes and Si - Coolmos in SMPS

Posted on 20 April 2015

      How do available SiC - transistors and GaN cascodes stack up against Si - Coolmos in real-world SMPS? Proven by extensive tests, neither SiC transistors nor GaN cascodes beat Si Coolmos. Alleged advantages of GaN are due to the cascode, not the material. By Dr. – Ing. Artur Seibt, Vienna Introduction and [...]

Using “Normally on” JFETs in Power Systems

Posted on 17 April 2015

      A “normally on” device can get short shrift at times due to the negative turn off voltage requirement. Supply Voltage sequencing and single point failures tend to make designers skittish, and thus bypassing the die size/resistivity advantages of “normally on” devices, and the capacitive advantages that go along with using devices with [...]

Web-based Simulation Tool to Simplify IGBT Selection and Thermal Design in Minutes

Posted on 16 April 2015

      By Kristofer Eberle, Plexim and Jiangmin Chunyu and Andrea Gorgerino, International Rectifier, An Infineon Technologies Company For a given voltage, current rating and package type, there can be many possible IGBT candidates. Additionally, the designer has to ensure that the power stage operates reliably within the thermal constraints. To alleviate these two [...]
