Later, the world’s first all-SiC powered traction system was installed in the Shinkansen Bullet Trains in Japan, as late as J. ![]() Their first com- mercially available product using SiC devices was launched mid 2011 in an inverter used in the home air conditioner "Kirigamine". Mitsubishi Electric started researching elemental SiC technologies in the early 1990s. SiC as a semiconductor material has been under development for over two decades. This article will provide a brief intro to the differences between Si and SiC devices used in power electronics. ![]() The use of Silicone Carbide (SiC) based devices promises a significant reduction in switching losses and permits far higher switching frequencies than what is possible today using pure Silicone (Si) devices. During the last few years a new generation of high power switches has emerged in the semiconductor industry and start to become commercially available.
