Wireless power transfer on domestic inducton hobs

In today's rapidly advancing technological landscape, significant progress has been made in the field of wireless communication and power transfer. Particularly, the wireless operation of small household appliances has accelerated research and development activities in this area. Induction cooktops present one of the most common examples of this wireless power transfer technology in everyday life. However, how this technology can be utilized to operate small household appliances and the practical advantages it may offer have not been fully explored yet. This study encompasses research aimed at wireless power transfer to small household appliances using induction cooktops. A system has been developed to harvest RF energy to power the user interface (UI) functions of small household appliances. NFC (Near Field Communication) at a frequency of 13.56 MHz has been preferred as the communication protocol. Before transitioning to the power transfer stage of the small household appliance to be energized via RF energy harvesting from the induction cooktop, the necessary energy for communication has been provided. The focus of the study is on separating the power transfer and communication channels. This method enhances the efficiency of power transfer while ensuring that communication signals are transmitted with minimal interference. This research demonstrates practical applications by combining wireless power transfer and communication protocols such as NFC, utilizing the magnetic field energy derived from induction cooktops. Within this study, a concept of wireless energy transfer capable of energizing small household appliances without sacrificing heating functionality has been proposed. The outcomes of this research could represent a significant step towards energizing small household appliances used in daily life in a more convenient and safer environment, without the hassle of cables, thereby enhancing user experience. Furthermore, it may inspire the development of new wireless power transfer and communication systems in the industry.
