PH9363NL and PH0416NL Applications

An isolated IGBT gate driver requires isolated power supply for safety isolation. Pulse Electronics Power BU’s flyback gate drive transformers deliver a distributed isolated supply to the Gate Drive circuits.

The PH9363NL and PH0416NL platforms are ideally suited for the following applications:

  • Powertrain Inverter
  • Electric Vehicles and Hybrid Electric Vehicles
  • Motor Drive Applications
  • MOSFETs and IGBTs drive circuitry

PH9363NL and PH0416NL Mechanicals & Schematics
