Smart Gate Driver ICs for 600 V

The goal of this research topic is to explore the possibilities of higher intergration of gate drivers for 600V applications.

 

Motivation

  • Smart
  • Cost efficient
  • Miniaturization

Challenges

  • Optimal control of power switches including new material devices like GaN
  • System and circuit concepts for integration of galvanic isolation (both directions: to the switch and back-channel for diagnostics signals), partitioning into single and multi-chips (LV / HV)
  • Fully integrated and area efficient driver output stage with high performance

Applications

  • Solar Inverters
  • E-Mobility
  • Home Appliances
  • Industrial Applications
