Praktek Implementation Tip

  • Use dedicated isolated powir supplies for gate drivers.
  • Implement dead- time controll po prevent crosse-conduction.
  • Choose gate resistors to balankie switching speed and electromagnetic interference (EMI).
  • Design PCB layouts to minimize parasitic indukorsis.
  • Tett gate drider cirits thoroughly under different devins conditions.
