WebDec 25, 2024 · The gate-to-emitter voltage ( VGE) is set to be 15 V in on-state, which is the same as the gate drive voltage of Si MOSFET and IGBT for integration, conveniently. The on-state voltage VON of the studied SiC IGBTs is defined as the VCE (when IC is 50 A/cm 2 and VGE is 15 V) in this paper. WebThe 15kV 4H-SiC MOSFET shows a specific on- resistance of 204mΩcm2at 25°C, which increased to 570mΩcm2at 150°C. The 15kV 4H- SiC MOSFET provides low, temperature-independent, switching losses which makes the device more attractive for applications that require higher switching frequencies.
