This paper proposes and implements an approach to achieve homogeneous heating in a single-source multiple-coil induction heating system. In a traditional induction heating system, one of the key disadvantages is the inhomogeneous heating effect. In particular, the heating power concentrates on a small ring area of the pan, while the outer part receives much lower power. The proposed induction heating system consists of two concentric coils with its compensated capacitors connecting in series, respectively. Currents in the two coils are controlled by newly employing the magnetic resonant coupling mechanism so that the heating power distribution in the inner and outer parts of the pan can be adjusted accordingly. Therefore, the proposed induction heating can achieve homogeneity and simplicity simultaneously by optimizing the operating frequency of only one inverter. Both the simulation and experimental results are given to validate the feasibility of the proposed homogeneous induction heating.
