This document discusses wireless charging technologies, including inductive charging, resonance charging, and radio charging. It provides details on how each works, such as using electromagnetic induction or radio waves to transmit power over short distances without wires. Applications are mentioned, like charging phones, electric cars, and other devices. Advantages include convenience and reducing electronic waste, while disadvantages are inefficiency over longer distances.

WIRELESS CHARGING WIRELESS TECHNOLOGY ASHWIN.V.N
CONTENTS  WHAT IS WIRELESS CHARGING?  WORKING.  TYPES OF CHARGING.  APPLICATION.  ADVANTAGES.  DISADVANTAGES.  SOURCE
WHAT IS WIRELESS CHARGING?  IT IS ONE OF THE METHOD USED TO CHARGE THE BATTERIES WITHOUT CABLES OR ADAPTORS.  THESE ARE USED IN WIDE RANGE OF DEVICES SUCH AS CELL PHONES ,LAPTOPS , COMPUTERS , MP3 PLAYERS , AND OTHER LARGER DEVICES SUCH AS ROBOTS , ELECTRIC CARS ETC.....
WORKING  THE MAIN COMPONENTS ARE :  TRANSMITTER.  ANTENNA .  RECIEVER.
BLOCK DIAGRAM OF WIRELESS TRANSMISSION
TYPES OF WIRELESS CHARGING  RESONANCE CHARGING.  INDUCTIVE CHARGING.  RADIO CHARGING.
RESOSNANCE CHARGING  IT USES THE PHENOMENON OF RESONANCE WHICH CAUSES THE OBJECT TO VIBRATE WHEN ENERGY OF CERTAIN FREQUENCY IS APPLIED.  TWO COPPER WIRES ARE USED TO TRANSMIT ONE AT THE TRANSMITTER AND ONE AT THE RECEIVER.  WHEN THESE COILS ARE PLACED CLOSE TO ONE ANOTHER POWER IS TRANSFERRED  EX: CARS,ROBOTS,VACCUM CLEANERS,LAPTOP AND OTHER DEVICES WHICH REQUIRE MORE POWER…
RESONANCE CHARGING IN ELECTRIC CARS
INDUCTIVE CHARGING  IT IS A KIND OF SHORT DISTANCE WIRELESS CHARGING IT USES THE CONCEPT OF ELCTROMAGNETIC INDUCTION .  WHERE THE CHARGER AND THE DEVICE WILL BE HAVING AN INSULATED COPPER WIRE ONE AT THE DEVICE AND ANOTHER AT THE CHARGER.  THE CHARGER CREATES ELECTROMAGNETIC WAVES USING COIL AND THIS WAVE IS SENT TO THE COIL OF THE PHONE OR DEVICE AND CONVERTS TO ELECTRICITY AND HENCE CHARGES THE BATTERY.  EX:MP3 PLAYERS , ELECTRIC TOOTHBRUSH, TRIMMERS ETC….
INDUCTIVE CHARGING IN PHONE
RADIO CHARGING  IT USES RADIO WAVES.  A TRANSMITTER PLUGGED TO SOCKET GENERATES RADIO WAVES AND RECIEVER IS ATTACHED TO THE DEVICE WITH SAME FREQUENCY AND THE BATTERY STARTS TO CHARGE.  EX:WATCHES , HEARING AIDS, WIRELESS KEYBOARDS AND MOUSE….
ADVANTAGES  PROVIDE CONVENIENCE TO CONSUMERS.  EASY TO MAINTAIN.  CHARGING OF MULTIPLE DEVICE AT A TIME.  AS IT IS WIRELESS IT IS ECONOMIC .  BETTER PORTABILITY.  ELECTRONIC WASTES WILL BE REDUCED COMPARED TO WIRELESS .
DISADVANTAGE  APPLICABLE ONLY FOR SMALL DISTANCES.  IT IS LESS EFFICIENT.  MORE POWER LOSS.  FOR LARGER DEVICES SUCH AS CARS ,STATIONS MAY BE LIMITED.
