In the era of technology, there is a constant increase in the demand for wireless technology which is environment-friendly. To use the wired network, lots of cables and ports are required to transfer the power. The users also feel that the wired network is messier and untidier. It is also not convenient for public use. Moreover, charging cables of the mobile phone usually will be fragile and breakable at some time due to the careless and poor handling by the users, wired network causes inconvenience to the users. In this project, the main objectives are to design and implement a wireless power transmission circuit. This principle of wireless power transfer works on the principle of using coupled resonant objects for transferring power. The resonance inductive coupling technique is the common method used to implement wireless power transmission. The 240V 50Hz AC power supply was given to the transmitting circuit where electromagnetic waves transfer the energy to the secondary coil from the primary coil. At the receiver circuit, 12V DC was produced to light up a 10W bulb at a specific range.
