This paper investigates the thermal impacts of electromagnetic proximity effects among the coils of domestic induction heating system (DIHS) with distributed planar spiral multicoils. A combined coordinates system is developed in the computation, consisting of a master Cartesian coordinate system and multiple slave cylindrical coordinate systems. The proposed computing method is implemented with different effecting parameters so as to analyze the impacts of proximity effects and eddy currents distribution in the DIHS. Computation results are validated through comparing against those from the finite element method (FEM). Furthermore, the temperature field is calculated to study the thermal impacts of proximity effects on the thermal distribution in the induction plate.
