要約(英語): In recent years, the demand for IH cooking heaters has grown as all-electric houses have become more common. The advantages of IH cooking heaters are high power, high efficiency, and safety. However, although the IH cooking heaters can heat a pan of iron or magnetic stainless steel, it is not effective for heating copper or aluminum pans. Aluminum pans account for approximately 30% of those used in homes. Therefore, IH technology that can be applied to heat all metal pans, including aluminum ones, is an important issue in terms of improving convenience. In this paper, we present a novel circuit topology for an IH system that is suitable for all types of metal pans. The proposed system changes the number of turns of the work coil according to the materials of which a pan is made, and changes the dc link voltage to add voltage to a single-ended push-pull (SEPP) high-frequency inverter. In magnetic pan heating, the proposed system controls the power through PFM control of the inverter, having reduced the number of turns of the work coil. On the other hand, in non-magnetic pan heating, the proposed system controls the power through PAM control of the dc link voltage, having increased the number of turns of the work coil.
