一种用于高开关电流利用率直流固态断路器的阻抗解耦栅极驱动方案

This letter presents a novel impedance-decoupling based gate-drive scheme for dc solid-state circuit breakers (SSCBs) targeting ultrahigh fault di/dt protection in densely configured dc grids. There are two major contributions. First, by separating gate-drive impedance for different sections of the solid-state switch turn-off process, the fault response speed of the SSCBs is significantly accelera...
