This paper proposes a new induction heating (IH) coil using Halbach-arranged coils for cooktop. In general, a control inverter is placed on the back side of the coil, but by using the Halbach array coils, magnetic flux leakage to the back of the coil can be prevented without using a ferrite cores for magnetic shielding. Further, the magnetic flux can be concentratedly linked to the pot. First, differences and advantages of the magnetic flux distribution between the conventional IH-coil and the proposed IH-coil will be described based on electromagnetic field analysis. Next, the results of verification of the effect of the Halbach array coil via the prototype for principle verification are demonstrated.

用于炉灶应用的 Halbach 阵列型感应线圈的建议和挑战


本文提出了一种使用 Halbach 排列线圈的炉灶新型感应加热 (IH) 线圈。通常，控制逆变器被放置在线圈的背面，但通过使用Halbach阵列线圈，可以在不使用用于磁屏蔽的铁氧体磁芯的情况下防止磁通泄漏到线圈的背面。此外，磁通量可以集中地连接至罐。首先，将基于电磁场分析来描述传统IH线圈和所提出的IH线圈之间的磁通量分布的差异和优点。接下来，通过原理验证样机展示Halbach阵列线圈效果的验证结果。
