Benefits

  • Push-Pull topology: Hard switching 45kHz.
  • 3 primary + 4 secondary transformer set.
  • Low leakage inductance.
  • Working volatge: Up to 4kVpeak.
  • Toroidal core to improve thermal performance and ensure uniform leakage inductance in all windings.
  • Physical isolation between windings (using plastic covers).
  • Use of high conductivity potting material: Less than 1,5 W/m·K.
  • High isolation can ensure 4000 Vpeak of partial discharge.
  • Good thermal capabilities even there is high isolation.
  • Slot cover design to maximimize heat transfer.
