Wireless Charging through microwaves

INRODUCTION


Portable electronic devices are basic part of our life.

Difficulties of carry a battery charger or an extra battery.

Energy harvesting-Gathering transmitted energy to power a circuit or storing it for later use.

It is a type of charging the battery with the help of microwaves present in the air using energy harvesting concept.

Abundance of energy all around us at all time.

Components Required


The design of the wireless battery charger consist of these major components;

Transmitter- In practical cases doesn’t need. Becouse
the mobile tower,radio stations etc replace it.

Charge pump-A circuit which convert AC to DC and elevates the DC level.

Antenna-In practical cases does’nt need. Mobile has itself.

Receiver-Consist a rectenna and a sensor circuit.

TRANSMITTER

Consist of a 915 MHz oscillator-capable of outputting a low AC signal.

Amplify the signal using an amplifier.

A radiating antenna is used to radiate the signal.

6mW of power radiated.
