N2 - Traditional induction heating cooktops typically employ a circular planar coil in resonance excited by a switching inverter. This configuration results in stray magnetic fields below the coil and non-uniform heating profile on the top. This paper presents the concept of multiphase, multi-resonant induction heating using a Halbach winding arrangement to eliminate the shortcomings of the traditional cooktop. A multiphase winding structure enables a traveling magnetic field at the target, which results in uniform heating profile. Operating the phases at different resonances deliver power at different frequencies. The winding and drive structure developed in this paper can be applied to many other applications, including chargers and wireless power delivery systems.
