摘　　要：家用电磁炉的效率和功率因数主要由加热线圈的等效电阻产生的有用功率、加热线圈的电感产生的无功功率和感应电流在锅底产生的实际加热功率三部分决定。文章用有限元软件对电磁炉的线圈、聚磁条和锅等结构进行了精确的三维建模,并分析了电流在有效值为20 A,工作频率分别为25 kHz、30 kHz、40 kHz的情况下效率和功率因数的变化情况。The efficiency and the power factor of the induction cooker will be determined by the relationship among the active power produced by equivalent resistance of heating coil,the reactive power generated by inductance the heating coil and the actual heating power generated by the induced current in the bottom of the pot.The winding,the poly strip and the pot are accurately built through finite element software.Changes of the efficiency and the power factor are analyzed at the case of the current effective value of 20 A,operating frequency of 25 kHz.30 kHz and 40 kHz.
