Power system 3 inverter
Power System - 3φ Inverter


Power system switches
Power System – Switches

  • Power MOSFET

    • high-frequency operation

    • low-voltage drop (low power losses)

    • saturation temperature sensitivity

  • IGBT

    • low drive current

    • fast switching time

    • higher voltage drop (higher conduction losses)

  • IGBT w/Diode Co-pack

  • Voltage - Collector Emitter Breakdown (Max): 600V

  • Current - Collector (Ic) (Max): 85A


Power system driver
Power System – Driver

  • Configuration: High and Low Side, Independent

  • Bootstrap circuit designed to prevent gate voltage from dropping below minimum gate threshold voltage
