Development of Wireless Charging for Mobile Application using PV Module

In this paper, a wireless power transmission (WPT) using resonant magnetic coupling for mobile phone charger is presented. Solar energy was used as the energy source to address the scarcity of non-renewable energy sources and tackles the constraints of wired charging technology such as lack of universal electrical standard, untidiness and inconvenience of wires and wires' wear and tear. The system includes PV panels and battery, oscillator, transmitting coil and receiving coil and rectifier. Proteus 8.1 was used to simulate before implementing in the hardware. The resonant magnetic coupling resonated at 800 kHz ± 10 kHz. The maximum distance to charge a mobile phone was 4 cm at 3.7 V. All the objectives are achieved within the limited time frame. The significance of the project can help to eradicate the use of wires and the need of power plugs. The future research includes the study of efficiency, coil design, system with multiple loads.
