Background Wireless charging will replace the wires and plugs same as to how Bluetooth and WI-Fi have made personal communication to be modern. Inductive coupling wireless charging used electromagnetic fields transferring energy to the receiver from the transmitter. Users are psyched up about the convenience this technology will bring. The consumers will simply place their mobile phones on top of a charging mat. The mobile phone battery wireless charger also works well with devices such as media players,digital cameras, Bluetooth headsets, and gaming controllers. Other applications that will use wireless charging system include medical devices, e-bikes, power tools, and electric cars. This modern technology is not new in the market. In 1831, Michael Faraday came up with Induction and he asserted that electromagnetic forces can move through a space (Pareek, 2006). Between late 1800 and early 1900, power transmission and wireless broadcasting were demonstrated by one man called NicolaTesla. Tesla was reluctant to provide a proof that the electricity could be transmitted without cables or wires. The project was halted due to lack of fund. In 1920, public broadcasting started, and Europe constructed massive transmitters having signal strengths to reach many countries. The transmitters in Switzerland transmitted electric power at 600 KiloWatts. The legislation on electric and smog, and protests from the domestic population lowered it to 180kW. Ever since, smaller stations have come to replace larger national transmitters. Figure 1: The Switzerland’s National Radio Station Mobile phone battery charging is related to radio transmission. The two are similar because they transmit power by use of electro-magnetic waves. Mobile phone battery wireless charging works in an almost similar field condition where the primary coil emits a magnetic field which is then picked by the secondary coil in very close proximities (Nicopolitidis, 2003). The radio transmitters operated on the -principle of far-field is sending electromagnetic waves traveling through space. The receiving coil of the chargers receives energy generated. The receiving antennae of mobile phones need few micro volts to increase the signal above the level of noise and capture clear intelligence when boosted. Therefore, when looking for means to clean cords off the countertop and make mobile device charging easy, then a mobile phone battery wireless charger is the appropriate device. These charge pads give the consumer the power to drop his mobile phone on a mat and start charging (Lin & Sou, 2008). The powermat chargers enable this by moving contact points needed for the transfer of electricity from the standardized port to the device back with special attachments or cases. For some consumers, this will mean adding battery door to a mobile phone. Some of these chargers differ in the count of devices accepted at an instance, and some have higher durability than others. Some of mobile phone battery wireless chargers include WildCharge Pad Energizer Inductive Charger Duracell myGrid Powermat 3X Proposed Methods The increasing demand of energy for mobile phones drives the urge for new methods in managing battery life. Wireless charging gives a chance by coming up with a common charging benchmark for various devices. It also offers infrastructure for their support. Wireless Charging therefore, offers intelligent, the software based technique of transferring power without wires. The wireless circuit provides both software and hardware with highly customizable characteristics, to offer maximum flexibility (Lin, 2005). Some of the target applications for this technology include the mobile devices, batteries, handheld radios, and automotive console. The available mobile phone chargers are expensive. Therefore the below circuit comes as a cheaper alternative to charging packs of mobile battery with rating of 7.2 V. The receiver circuit is as shown below: The circuit is s08P: 8-bit 7V eeprom with TSI MCUs. The circuit is Qi-based and it is highly customizable; can be highly configured through the software. Some of the advantages of the circuit are that it can be quickly customized and deploy the preferred solutions by offering a reduced time-market charging system. It also provides industry compatibility by providing Qi-based solutions. Consequently, the circuit is market driven reference designs for faster enabling The transmitter circuit is as shown below: The product is 56f824x_825X: Digital Signal Controller . The product consists of customized configurations or Qi. The product is highly used DSC core technology for the PID execution of the control loop. Some of the advantages of the above product are that, it has a wide flexibility by providing turn-key or very highly customizable charging system. Additionally, it is highly integrated, providing a decrease system complexity and at a lower cost. Results The transmitter circuit has a tank circuit output that feeds into a rectifier. The output goes through the regulator to become VIN for the CBC3150. When VIN exceeds 3V, the harvested power is routed to the connector that is harvesting energy J3. At this particular point, the CBC3150’s pin 8 goes higher. The 220 Volts Alternating Current supply are lowered to 7 Volts Alternating Current by transformer X1. The diodes D1 rectifies the output of the transformer through D4 that is wired by bridge configuration. The +ve Direct Current Supply is connected to the output of the charger’s contact, while the negative terminal is connected through resistor R2. LED2 operates as the power indicator while resistor R1 acts as the current confiner and LED3 shows the charging status. During the charging time, about three Volts drop happens across resistor R2. It later turns on LED3 through R3. The external 12 Volts Direct Current supply origin can be used as charger energizer, where R4, after the protection of the polarity, diode D5 will limit the input current to a protected value. The three-terminal voltage regulator offers a constant output voltage of 7.8V Direct Current which is connected between the ground rail and the common terminal. This will later raise the output to 7.8Volts Direct Current. LED1 will serve as the power indicator for the outside supply (Easton, 2002).
