Abstract. The effect of silicon carbide (SIC) electronics operating temperatures on Power Management and Distribution (PMAD), oi Power Conditioning (PC), subsystem radiator size and mass requirements was evaluated for titree power output levels (100 kWh, 1 MW_, and 10 MW_) for neat term teclmology (i.e., 1500 K turbine inlet

Gallium Nitride (GaN) versus Silicon Carbide (SiC)

The table below compares material properties for Silicon (Si), Silicon Carbide (SiC-4H1) and Gallium Nitride (GaN). These material properties have a major influence on the fundamental performance characteristics of the devices. Both SiC and GaN have material properties superior to Si for RF and Switching Power devices.
