Abstract

The analysis of the magnetic properties of alloys with low Curie temperature used in domestic induction heating is presented. These alloys allow the development of cookware with additional benefits with respect to regular cookware oriented to improve temperature control and the user’s safety. Firstly, an experimental method to characterize the magnetic permeability with respect to the magnetic field strength and temperature in the material is presented. Secondly, a finite element simulation method is proposed which, considering the previous characterization, allows the calculation of the electrical equivalent of an inductor-load system as a function of temperature and magnetic field. This method makes possible the application of finite element simulation in the frequency domain with nonlinear materials, which is of interest for the design of electronics associated with domestic applications of induction heating. Simulation results are experimentally verified with various ferromagnetic alloys with low Curie temperature at different power, temperature, and operating frequency ranges.

应用于家用感应加热的低居里温度材料的磁非线性研究

本文分析了用于家用感应加热的低居里温度合金的磁性能。与普通炊具相比，这些合金使炊具的开发具有更多优势，可改善温度控制和用户安全。首先，介绍了表征磁导率与材料中磁场强度和温度关系的实验方法。其次，提出了一种有限元模拟方法，考虑到之前的表征，该方法可以计算出电感器负载系统的电气等效值与温度和磁场的函数关系。这种方法使有限元模拟在非线性材料频域中的应用成为可能，这对与感应加热家用应用相关的电子设备设计很有意义。模拟结果在不同功率、温度和工作频率范围内通过各种低居里温度铁磁合金进行了实验验证。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
