State of the SiC MOSFET

State of the SiC MOSFET
It is highly unlikely that anyone reading this article is unfamiliar with the Insulated Gate Bipolar Transistor (IGBT). This disruptive power transistor, first commercialised in the early 1980s, has had an enormous positive impact on the power electronics industry, enabling innovative converter design, improved system efficiencies, and worldwide energy savings. Indeed, some estimates suggest the IGBT has helped forestall 75 trillion pounds of CO2 emissions over the past 25 years.
