Around 4-5 years ago, SiC MOSFETs or GaN HEMTs in the 650V range would cost about 4 -5 times the price of a similar voltage, current, and R DSON-rated Si SJ MOSFET. WBG device prices have dropped over the last few years as wider adoption leads to efficiencies from volume production and greater competition.

For power metal-oxide-semiconductor field-effect-transistors (MOSFETs), there are two current paths in the 3rd-quad conduction, namely the MOS channel path and the body diode path. It is well known that, for 1.2 kV silicon carbide (SiC) planar MOSFETs, the conduction loss in the 3rd-quad is reduced by turning on the MOS channel with a positive ...

In case of SiC MOSFET, higher gate-source voltage is required as compared to Si MOSFET because SiC carrier mobility and channel resistance are lower and higher, respectively in comparison with the Si. Higher the gate-source voltage lowers the drain-to-source resistance which gets saturated at a voltage of 18 V. If SiC is driven by the gate ...

SiC materials costs scale up at with the voltage range, and these can be estimated, as follows. Based on the prices of thick epitaxy available to this author in 2020 (albeit on small order sizes), a SiC substrate with 100 µm of epitaxy, as required for 10 kV SiC MOSFET development, was over 4x the price of a 10 µm, 1200 V substrate.
