Positioning the vehicle during wireless charging either it is static or dynamic is important as it plays the key role in transfer efficiency. During wireless power transfer, the two coils which are present on primary side and secondary side must be aligned perfectly. An Inductive power transfer circuit is designed to analyze the transmitting and receiving voltages at different coupling factors and a new radio alignment technique is proposed where it uses hall effect sensors which are placed on the secondary side and are used to sense the voltage generated by primary side and based on the active states of the sensors, driver is guided to move in a direction for better transmission. The problem in misalignment is analyzed and a logical circuit is designed to guide the driver to align the vehicle.
