| Abstract |
Development and technology maturation of Silicon Carbide (SiC) power transistors over the last 15years has motivated its study in aerospace systems. When compared with Si devices, superior voltageblocking capacity and the capability of operation at higher temperatures, give important advantages inspace power electronics applications, similar to what happens in terrestrial electronics.This paper discusses the use of SiC power transistors for Solid State Power Switches especiallyaddressed to the space segment. Two applications will be covered, the first is the Solid State ShuntSwitch, widely used in high power Direct Energy Transfer (DET) photovoltaic power regulators and thesecond is the Solid State Series Switch, which has been identified for high voltage (up to few kV)protection systems. |
