    This paper proposes a novel square 9-coil (3×3) matrix system for induction cooking applications in order to improve the heating performance. By means of finite element method (FEM) analysis, three different exciting modes for the proposed system are thoroughly investigated. The magnetic field and eddy currents distribution are studied for each case. Furthermore, thermal field computation is conducted to analyze and compare the heating performance for the proposed system with different exciting modes. The thermal field computation results indicate that the proposed square 9-coil system can effectively and significantly enhance the heating performance in terms of better uniformity and heating efficiency over conventional single coil systems.
