Short Circuit Protection for SiC with Isolated Gate Drivers

Achieve reliable and fast short circuit protection (SCP) on SiC power devices using isolated gate drivers, and obtain a panoramic view of the short-circuit protection needs for SiC used in EV and renewable energy applications. We will discuss protection requirements from a SiC device perspective and explain the gate driver timing and functionality requirements. We will also present bench test results using ADI isolated gate drivers to protect Wolfspeed SiC power modules.
