Abstract

This study presents the development and performance evaluation of a wireless power transmission module based on electromagnetic induction principles. The system comprises of a transmitter unit, designed to enable efficient contactless energy transfer for low-power portable applications. The transmitter module is powered by a 220 V AC mains supply, which generates a 48 kHz oscillation circuit. The oscillator generates a high-frequency square wave signal that drives a transmitting coil, producing an alternating electromagnetic field for wireless energy transfer. Performance evaluation was conducted in terms of output voltage stability, transmission efficiency, operating frequency characteristics, and load response. Experimental results demonstrate reliable power transfer, low acoustic noise operation, and satisfactory efficiency for short-range wireless charging applications. The developed module provides a practical and scalable solution for compact wireless power systems.
