    7. PRODUCT ACCESSORIES 7.1. Saucepan Recognition System In induction cooking, only the area covered by the vessel on the relevant cooking zone is energized. Vessel's bottom is recognized by the system and only this area is heated automatically. Cooking stops if the cooking vessel is lifted from the cooking zone during cooking.
  • Page 23: Induction Working Princible

    8. INDUCTION WORKING PRINCIBLE Operating principles: Induction hob heats directly the cooking vessel as a feature of its operating principles. Therefore, it has various advantages when compared to other hob types. It operates more efficiently and the hob surface does not heat up. Advantages of Induction Cooking Fast cooking: Heat is generated directly in the vessel thanks to the induction technology.
  • Page 24 Figure1: Induction control system Resonance converter: Aim of the resonance converter design is making switching at no voltage and no current. Sharing energy between capacity and inductance provides power adjusting. Maximum power is transfered at resonance frequency. There are three types of converter: serial, paralel and serial-paralel..
