Planar coil for induction cooking

 

 Inductive Conductor Requirements

  •   high frequency properties (25 – 50 kHz)
  •   high temperature resistance
  •   superior break down voltage performance
  •   great mechanical strength
  •   high filling factor  (compressed winding) 
  •   single wire diameter 0.20 - 0.40 mm

 

Typical Litz Wire for Inductive Cooking Hobs

 

  • Main material

              copper

 

  • Low/medium number of strands

               30 - 120 (depending on the size/type of the cooking hob)

 

  • High temperature resistant enamel (approx. 200°C)
                   (Optimization of break down voltage and thermal resistance)

 

  • Optionalprofilation

              (Optimization of filling factor)
