Abstract
Conventional induction heating (IH) system have been developed to heat the pot of ferromagnetic materials, because the small resistance of non-ferromagnetic materials induces large resonant current to the power switch of a series resonant IH inverter. However, the heating capability for various materials is the most important to improve the functionality and the usability of IH products. In this paper, a load adaptive modulation (LAM) method is proposed to heat the pot made from non-ferro and ferromagnetic materials. The LAM method can change the magnitude of the input voltage of the IH coil and the operating frequency of the series resonant IH inverter according to the resistance of the pot. The operational principle and the design method are analyzed to implement the proposed LAM method and its power control. The validity of the LAM method is experimentally verified using a 2 kW prototype series resonant IH inverter.
