Proposal and Challenge of Halbach Array Type Induction Coil for Cooktop Applications

This paper proposes a new induction heating (IH) coil using Halbach-arranged coils for cooktop. In general, control inverter is placed on the back side of coil, but by Halbach array coils, magnetic flux leakage to can be prevented without ferrite cores shielding. Further, concentratedly linked pot. First, differences and advantages distribution between conventional IH-coil proposed will described based electromagnetic field analysis. Next, results verification effect via prototype principle are demonstrated.
