Design and Development of Wireless Power Transmission System Optimization Using Spiral Coupled Inductor Based on IoT and Electromagnetic Induction Principle

Abstract

Wireless Power Transfer (WPT) constitutes a system designed to distribute electrical power without the utilization of cables as the connecting medium between the power source and the load. This system employs air as the transmission medium for energy via a sending circuit, referred to as a transmitter, and a receiving circuit known as a receiver. The methodology implemented involves the transfer of electrical energy through electromagnetic induction, wherein both circuits are equipped with coils for the transmission of electrical energy. An innovative aspect of this system is the incorporation of LCD and IoT technology for the monitoring of parameters such as voltage, power, and current, as well as for optimizing the distance between the coils and the load. The findings of the study indicate that at a distance of 0 cm between the coils, the WPT system based on electromagnetic induction is capable of transferring electrical energy with a maximum voltage of 18.81 V, a power output of 2.73 W, and a current of 0.145 A. Conversely, at a distance of 24 cm between the coils, the minimum recorded values are 2.94 V for voltage, 0.01 W for power, and 0.001 A for current. The load utilized in this experiment was a 3W LED bulb.
