If i can have i will be grateful

1. Wireless mobile charger PRESENTED : C.BUILUNGCHHUI ROLLNO: ECE 22 04

2. WHATSCONTENTS WHAT IS WIRELESS CHARGING TYPES OF CHARGING DESIGN OVERVIEW APPLICATIONS ADVANTAGES LIMITATIONS CONCLUSIONS REFERENCE

3. WHAT IS WIRELESS CHARGING Wireless charging is one of the several methods of charging batteries without the use of cable or device specific AC adaptors Wireless charging can be used for a wide variety of devices including cell phones laptop computers and MP3 players as well as larger objects such as robot and electrics cars

4. Methods of charging There are three types of wireless charging Reasonance charging Inductive charging Radio charging

5. Design overview The basic design mainly consists of three sole parts: Transmitter Antenna Receiver

6. applications Wireless charging pad for mobile devices

7. Others applications Inductive coupling –RFID In-vehicle charging Radio charging Ultra Wideband

8. benefits Provide consumer with freedom and convienience The Way the technology works is simple Simultenous charging of multiple devices The plastics,packaging and electronic waste associated with charge is greatly reduced Since it is wireless,it is economic

9. Limitations Applicable for only small distance For the larger devices like electric car ,charging station may be limited Efficiency and power loss are the major problems

10. conclusions Research into using wireless technology to supply to terminals is finally beginning to be realized. The technology provide awide range og other obvious benefits,including better portability,lower costs and best off all the end of the having to quess which charger go what gadgets. Charging will one day become a simple matter of dropping devices into the nearest charging pad
