Предложена архитектура гибридной системы питания, разработан в виде диаграммы алгоритм последовательности работы адаптивного управления. Это в совокупности позволило обеспечить эффективное энергоснабжение датчиков системы IoT. Основной проблемой была идентификация высокой нелинейности импеданса выпрямительной системы, зависящей от входной мощности, частоты и параметров DC-DC-преобразователя, что делает традиционные подходы к согласованию цепей неэффективными в широкой полосе частот Wi-Fi.</p></abstract><trans-abstract xml:lang="en"><p>This article examines methods for improving the energy efficiency of IoT edge devices, including hardware solutions, wireless powering via Wi-Fi, communication protocols, energy management algorithms, and the use of renewable energy sources. A hybrid power system architecture is proposed, and an adaptive control sequence algorithm is developed as a diagram. Together, these factors ensure efficient power supply to IoT system sensors. The main challenge was identifying the high nonlinearity of the rectifier system impedance, which depends on the input power, frequency, and DC-DC converter parameters, making traditional approaches to mat­ ching circuits ineffective over the wide Wi-Fi frequency band.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>IoT</kwd><kwd>энергоэффективность</kwd><kwd>Wi-Fi Energy Harvesting</kwd><kwd>гибридная система</kwd><kwd>ESP32</kwd></kwd-group><kwd-group xml:lang="en"><kwd>IoT</kwd><kwd>energy efficiency</kwd><kwd>Wi-Fi Energy Harvesting</kwd><kwd>hybrid system</kwd><kwd>ESP32</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Lu X., Pi Guo (2016) Wireless Charging Technologies: Fundamentals, Standards, and Network Applications.
