A Quasi-Multilevel Gate Driver for Fast Switching and Crosstalk Suppression of SiC Devices

open access: yesIEEE Access, 2020
The crosstalk phenomenon in a phase-leg configuration forbids the operation of SiC devices at high switching speed. A multilevel gate driver (MGD) is well-known for crosstalk mitigation, however, it requires two driver ICs and two voltage supplies to ...
