Extract of sample
The wireless power enables the electrical energy to be transmitted from the source of power to an electrical load. The system operates without connecting wires. The system is important because it is used in places where interconnecting wires are impossible, inconvenient, or hazardous. A mobile Phone Battery wireless charger is a system that charges mobile phone battery using a wireless charger. The idea behind wireless charging is to plop the device on the shelf and have it charged. The technology replaces cable wiring and standardize on a single interface. Additionally, the interface will be able to adjust the power setting to charge various types of batteries. The mobile phone battery wireless charged has two circuits; receiver circuit and transmitter circuit. The transmitter circuit has a step down transformer of 230V to 12V (“Wireless technology prospects and policy options”, 2011).
The transformer steps down 230 Voltage from 12 Volts. Consequently, the 12V AC is then converted into 12 Voltage DC by a bridge rectifier. A 2200/25V capacitor then filters ripples and pure Direct Current is supplied. The oscillator circuit with the assistance of transmitting coil, will oscillate at 10MHz, thereby transmitting the wireless power. The receiver circuit will then receive the power with the help of a receiving coil and flow through the circuit of a voltage multiplier (“USB Cellphone Charger circuit”, 2008).
. The voltage multiplier circuit consists of the capacitor voltage multiplier and diode. ...
