Input and Output Chokes

Input and Output Chokes

Mid-power range chokes, for various high frequency switching applications. Copper foil, flat and round wire, combined with several magnetic materials (soft ferrite, Sendust, iron powder, amorphous) and multiple formats (E-cores, C-cores, toroidal) allow Prax to meet virtually any customer requirement.

  • 3ph-inductance 150uH 86Arms
    3 phase AC input inductance used in a 50kW car battery charger. Made with amorphous segments core with silicone potting in a custom aluminium box for mechanical fixing. Includes a bimetallic thermostat for temperature control.
  • Buck Inductor 2,2uH 67A
    Buck inductor in PQ format with flat Cu wire to allow high density currents. Used in a electric car application.
  • Buck Inductor 950uH
     
  • Choke 24uH 200A
    Full bridge choke for welding application. Using three EE85 stacked cores with stainless steel ties to enhance sturdiness.
  • DC Choke 145uH
     
  • DM inductor 3,3uH 16Amps
    Differential mode choke with raised profile box to allow potting material and requested pinning layout to ease mounting.
  • 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.
  • PM87 Resonant Inductor 38uH
    Designed and optimised for a 3-phase 12.5KW battery charger, this inductor is used in a 4.2kW converter with resonant topology. It is made of a PM87 ferrite format and winding is made with bifilar 1200×0.07 litz wire.
  • Resonant Choke 150uH Multigap
    Multigap choke in toroid form. Formed with split windings to asure dielectrical strenght between outputs. Spècially made to pass partial discharge at high voltage. Low AC losses due to core construction reducing fringing effect.
  • Toroidal Inductor 22uH
     
  • Toroidal Inductor 830uH
     
  • 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.
