Abstract: This system demonstrates the concept of wireless mobile charging system using the principle of inductive coupling. The system allows users to wirelessly charge their mobile phones without plugging in the mobile adapter. The system is demonstrated using a charging pad where users just need to place their adapter circuit to charge the mobile phone. For this purpose the advanced power transfer concept is utilized. A high frequency transformer is used to convert mains input 230V AC to 12 V DC. This output is supplied to the charging pad coil. When the adapter coil comes in range of the charging pad coil, the power is thus transferred wirelessly to the receiving coil and this 12 V DC is provided to the adapter circuit which is used to convert this 12 V DC to 5V DC which is then supplied to the mobile phone. So this allows us to charge the mobile phone wirelessly without plugging it in. The system can be further enhanced by integrating the charging adapter within the mobile itself so that users will just need to place their mobile phones on the charging pad to charge it
