Analytical design of a high-speed SiC MOSFET gate driver
using isolated class-E inverter
<Abstract> This paper proposes a high-speed SiC MOSFET gate driver with the isolated class-E inverter. Analytical expressions of the proposed driver are given and design procedure using the analytical expressions is presented. A SiC MOSFET is driven by a sinusoidal drive voltage because the proposed driver is a resonant driver. 7 MHz isolated class-E driver for SCT2450KE SiC MOSFET is designed. Experimental and PSpice-simulation waveforms are agreed with the analytical ones quantitatively, which showed the validity of the analytical expressions and design procedure. |
