Optimal Design and Finite Element Simulation of Induction Cooker Magnetic Circuit

摘要

Based on the analysis of the structure and principle of the induction cooker heating, combined with advanced finite element numerical simulation software at present, this paper established a two-dimensional simplified magnetic circuit simulation model of induction cooker. The paper carried on a series of calculation and analysis on the density distribution of the eddy current loss of induction cooker, and further studied the influence of the structure form, magnetic material, shape and size on magnetic circuit and energy efficiency of induction cooker, finally designed a new type of induction cooker coil and magnetic core. The results of finite element simulation calculation and experiment validation indicated that new type of induction cooker magnetic circuit possessed the characteristics of higher energy conversion efficiency, less leakage magnetic field and uniform heating.
