A Dutch solar car team from University of Twente and Saxion Hogeschool has selected silicon carbide (SiC) devices from UnitedSiC ahead of a major solar racing challenge in October. UnitedSiC provided product samples of their FAST Series of SiC FETs to Solar Team Twente, which they selected on the basis of superior performance.

Silicon carbide varistor For this we take MOV metal-oxide varistor which is the most common type of varistor. This type contains a ceramic mass of zinc oxide grains, in a matrix of other metal oxides (such as small amounts of bismuth, cobalt, manganese) sandwiched between two metal plates (the electrodes).
Armed with tough computer chips, scientists are ready to return to the hell of Venus By Paul Voosen Nov. 22, 2017 , 9:00 AM CLEVELAND, OHIO—In an underdog city, at an underdog NASA lab
Transistors made of silicon carbide—which has an even wider bandgap, in excess 3 eV—can work at over 500 C, but those devices have yet to be tested for longevity.
A coined cycle power plant is an assely of heat engines that work in tandem from the same source of heat, converting it into mechanical energy. On land, when used to make electricity the most common type is called a coined cycle gas turbine (CCGT) plant. The same principle is also used for marine propulsion, where it is called a coined

GaN-on-silicon E-HEMT transistors are the choice for maximum performance, efficiency and cost-effective power supplies. Cost-effective driver technology enhances supply performance by simplifying layout, reducing component count, and improving reliability.
Designers can reduce component count by moving from silicon-based, three-level topologies to simpler two-level topologies made possible by the 1000 Vds rating of the SiC MOSFET. The increase in output power in a reduced footprint is realized by the ultra-low output capacitance ―as low as 60 pF― which significantly lowers switching losses.
