Wireless Power Transmission Systems: A Review

Gayatri Mohanta

Abstract


The wireless power transmission system combines three parts: the transmitter antenna, free space channel and receiver antenna. The first part is the transmitter antenna in which an RF source is present, the transmitter antenna converts electrical signals to microwaves. After transmission from the transmitter antenna, the focused microwave beam carries the RF power and travels through free space and moves towards the receiver antenna, where the receiver antenna receives the RF energy for the conversion to DC electricity. There is a matching impedance circuit and rectifier circuit between the receiver antenna and load. There is an equivalence between the transfer function and the efficiency of the system. Efficiency is the ratio between output power to input power, whereas overall efficiency is the ratio between DC output power at the receiver to the DC/AC input power at the transmitter side.
