Universidad de Zaragoza Self-adaptive overtemperature protection materials for safety-centric domestic induction heating applications 2023 Access copy available to the general public Unrestricted Security aspects in the household sphere have become a major concern in modern societies. In particular, regardless of the technology used, users increasingly appreciate a protection system to prevent material damage in the case of human errors or distractions during the cooking process. This paper presents a sensorless method for detecting and limiting overtemperature, unique to induction cooktops, based on their specific features, such as automatic pot detection and load power factor estimation. The protection system exploits the change in the load material properties at certain temperatures, the effect of which may be enhanced by arranging a multilayer structure comprising a low Curie temperature alloy and an aluminum layer. The proposed multilayer load exhibits two differentiated states: a normal state, where the cookware is efficiently heated, and a protection state, above the safety temperature, where the power factor abruptly decreases, limiting the overheating and making the state easily detectable by the cooktop. This method of overtemperature self-protection uses the electronics of conventional induction cooktops; therefore, no other sensors or systems are required, reducing its complexity and costs. Simulation and experimental results are provided for several cookware designs, thereby proving the feasibility of this proposal. info:eu-repo/grantAgreement/EUR/AEI/CPP2021-008938 info:eu-repo/grantAgreement/EUR/AEI/TED2021-129274B-I00 info:eu-repo/grantAgreement/ES/ISCIII/PI21-00440 info:eu-repo/grantAgreement/ES/MICINN-AEI/PDC2021-120898-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2019-103939RB-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.4 2023 COMPUTER SCIENCE, INFORMATION SYSTEMS 87 / 250 = 0.348 2023 Q2 T2 TELECOMMUNICATIONS 47 / 119 = 0.395 2023 Q2 T2 ENGINEERING, ELECTRICAL & ELECTRONIC 122 / 353 = 0.346 2023 Q2 T2 0.96 2023 Engineering (miscellaneous) 2023 Q1 Materials Science (miscellaneous) 2023 Q1 Computer Science (miscellaneous) 2023 Q1 9.8 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Acero, J.
