Abstarct: Induction heating technology is currently used in many industries, home appliances and medical applications due to advantages such as high efficiency, fast heating, safety, cleanliness and accurate control is used. These systems usually consist of inverter, inductor and a piece of mextal. By passing alternating current through the coil, an alternating magnetic flux in the three parts of the workpiece, air gap and copper will flow, the alternating magnetic field induces eddy currents in the bottom of the pan, and the pan heat up, according to Jule's law. In this study at the beginning a designing algorithm has referred. In this algorithm factors such as the diameter of each strand conductors, temperature of each stranded conductor, the number of rounds, pan’s material and the distance between pan and winding have been investigated. During the supervision, finite element (FEM) tool was used to simulate and a circuit for modeling of coil performance in Matlab is introduced. The impact of the switching frequency and duty cycle on heat penetration in the work piece is examined.
