This document summarizes a project on wireless power transmission using inductive coupling between two coils. The system transmits power from a transmitting coil connected to an AC power source to a receiving coil connected to a load. At the transmitter, AC power is converted to a magnetic flux using an oscillator and primary coil. This magnetic flux induces an EMF in the secondary coil at the receiver, transmitting power wirelessly. The system provides advantages over wired transmission like eliminating wires and allowing power transmission over distances without connections. Various applications are discussed including charging devices and electric vehicles wirelessly.
