The ED-WP-CB is a high-performance digital gate driver core developed by Firstack for NPC I-type 3-level system. It supports the operation of up to 1700V EconoDUALTM IGBT power modules with 15V gate voltage in on-state.
The gate driver adopts CPLD as the digitally controlled core, with complete protection functions and built-in fault management system, which uploads the converter's operating state to the master computer in real time, providing support for big data management for the failed converter site. Perfectly solving the two major problems of turn-off timing sequence and large commutation loop turn-off spike in NPC I-type topology, the reliability of NPC topology can be comparable to 2-level, allowing customers to use NPC I-type 3-level as same as 2-level.
