Wolfspeed C3M MOSFET’s have been thoroughly optimized for Vgs(+)= 15V operation and the benefits of operating at Vgs(+)=18V are minimal. Furthermore, operation at Vgs(+)> 15V causes unnecessary gate stress which we do not recommend. Wolfspeed has worked with our partners to develop drivers optimized for Vgs=15V/-4V operation. While a Vgs(+)=15V gate drive circuit is always recommended, Wolfspeed has prepared some simple power supply design options for interoperability between various positive and negative Vgs voltages.
