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. 

  • Understand the protection requirements of SiC power devices.
  • Appreciate the roles of individual blocks in isolated gate drivers that aid in protecting the SiC device.
  • Design techniques for fault detection loops to ensure reliable operation.
  • Setting accuracy expectations of DESAT based protection for SiC.
