Gate Drive Considerations A key simplifiion using SiC FETs is that in the low voltage MOSFET has a 5V threshold V TH, and a V GS(MAX) rating of +/-25V. It can be driven like a silicon superjunction MOSFET from 0 to 10V (or 12V).
Silicon carbide, also known as SiC, is a semiconductor base material that consists of pure silicon and pure carbon. You can dope SiC with nitrogen or phosphorus to form an n-type semiconductor or dope it with beryllium, boron, aluminum, or gallium to form a p-type semiconductor.

Silicon carbide (SiC) has excellent properties as a semiconductor material, especially for power conversion and control. However, SiC is extremely rare in the natural environment. As a material, it was first discovered in tiny amounts in meteorites, which is why it is also called “semiconductor material that has experienced 4.6 billion years of travel.”
Owing to the faster switching speed of silicon carbide devices further demands are put on the serialisation method. In this study, a cascaded series-connection method using only a single external gate signal is analysed in detail, guidelines to size the resistor–capacitor–diode-snubber are proposed and its applicability is experimentally demonstrated.

Power Integrations created an isolated gate drive system for up to four paralleled 1.7-4.5kV power modules - either IGBT or silicon carbide mosfet. Called Called Scale-iFlex, it is dual channel so, for example, independent control of high and low-side switches in a half-bridge is possible.

Isolated gate drivers enable low-voltage microcontrollers to safely switch high-voltage power transistors on and off. Safe switching of high-speed Silicon-carbide (SiC) and Gallium-Nitride (GaN) transistors places an extra requirement on isolated gate driver ICs: high common-mode transient immunity (CMTI).
Key Points: ・In order to obtain a low on-resistance for a SiC-MOSFET, the Vgs must be set higher than that for a Si-MOSFET, to around 18 V or so. ・The internal gate resistance of a SiC-MOSFET is higher than that of a Si-MOSFET, and so the external resistance
US and Int. Patents & Patents Pending Advanced Control cont. •An alternate method is to use a programmable gate resistor array. –The switching starts off with a low gate resistor value, increases as the miller plateau is reached and reduces again. 1/7/2018
