Abstract

Wireless power transfer technology provides a convenient and safe alternative to conventional wired charging systems. This paper presents a frequency-controlled inductive wireless power transfer system designed to improve power transfer efficiency under varying operating conditions. The proposed system employs resonant inductive coupling between transmitter and receiver coils tuned to the same resonant frequency. A high-frequency inverter converts DC supply into AC, which excites the transmitter coil to generate a magnetic field. The receiver coil captures this magnetic field and induces voltage, which is rectified and filtered to obtain DC output. To maintain resonance, frequency control is implemented using a DSP-based adaptive approach modeled in MATLAB. The controller dynamically adjusts switching frequency based on output power to maximize efficiency. The system is validated through simulation and hardware prototype. The proposed design demonstrates efficient short-range wireless power transfer suitable for applications such as two-wheeler electric vehicle charging.
