SMPS transformers

SMPS transformers

Switch-mode power supply main transformers requirements depend on power range, topology, isolation and frequency. Therefore, a wide range of materials, formats and winding technologies are available. Our aim is to optimize size, efficiency and cost.
Designs available for topologies such as flyback, forward, push-pull, half-bridge, full-bridge and advanced resonant topologies.

  • EF25 Flyback Transformer
  • EFD30 Flyback Transformer
  • Flybuck transformer 12V:12V 53uH
    EFD20 transformer with SMD format. Covered with Kapton tape to assure 4kV isolation between primary and secondary.
  • Full Bridge Transformer 50kW 1mH 800V 24kHz 1:1:1
    Full bridge transformer for a 50kW system for a car charge application.
  • LLC Resonant (Transformer + Inductor)
    LLC set including transformer and inductor in the same mechanical custom box. Specially designed to reduce switching losses. Transformer with very low leakage inductance with triple isolated litz wire. All materials are Class F. Silicon potting to avoid damaging the cores.
  • PQ3535 LLC Transformer
  • PQ50 Full Bridge Transformer
    Specially designed for air leads, this full bridge PQ50 transformer combines bifilar Cu foil winding with split primary made of 8×0.63mm wire. Metal clip is used for extra mechanical vibration resistant build.
  • Push-pull Transformer 400/12V 3.6 kW
    Using PQ45/45 format with high current at secondary winding. Copper foil plated to avoid rust. Double isolated litz wire, output with terminal atteched by hot crimping. DC/DC side of an on board charger.
  • Set Full Bridge PS transformer 20kW 100kHz
  • Transformer + Inductor set 11kW
    LLC set multigap. Primary and the inductor connected without external connection to reduce ringings due to capacitance. Compact design for a 10kW system. Using triple isolated litz wire and plastic separator between turns to reduce coupling capacitance in the same winding.
  • Transformer 2xE71 6KW
    Used in a 6kW inverter, this transformer uses double E71 format winding with a combination of Cu foil and litz wire. With a custom aluminium base, it offers enhanced mechanical robustness.
