Date: November 3, 2016

How the best combination of MOSFET and gate act together to develop a competitive high performance power stage solution:

  • Power stage system design aspects 
  • Effect of ON state resistance of MOSFET 
  • Effect of gate charge of the FET 
  • Gate driver controlling the slew 
  • Challenges associated with very fast MOSFET turn on 
  • How gate driver can protect inverter against dv/dt turn on? 
  • Design challenges: switch node ringing and ringing reduction
