Literature Review on Engineering - Research Paper Example

Literature Review Insert Literature Review Power or energy can be transferred using various wireless means which have been known and researched on over the years and which are known as far –field means of energy transfers. The transferring of energy using the method of radiation as employed in the operations of the radio waves and radiations. However this form of energy transfer proves to be inefficient since just a small portion of the radiated energy is picked up by the receivers. Some amount of the radiation is radiated into space and lost in the air.

The wireless battery charging system therefore should employ the use of antennas that confine the waves towards a specific point of reception hence efficiency. The device therefore is unidirectional and stationary with the ability to raise resonators that are efficient within the mid ranges. (Kerallis, Campanella, Condkrad, & Morris, 2006) The wireless rechargeable battery has patent in the USA and it employs a power supply with an alternating current flow that supply direct current. The device has a design enabling it to receive to receive energy from a supply that is wirelessly connected to it.

The components include an indicator, a wireless charging module, and a battery unit. The wireless supplies of energy efficiently transform the energy into electricity with the ability to perform the function of charging the battery. Most of the common electronic devices including the notebook computers are employing the use of energy supply of indirect currents connecting with the indirect current to provide the necessary energy for the running of the device. The use of the power supply which might be bulky especially during movements and travels is very bulky for the operating of the devices hence the necessity of the use of the wireless chargeable battery to run the respective devices efficiently despite the location of the individual without the related heavy machinery for charging the systems.

The control system of the wireless charging system will include the switch and an indicator that makes the operator to understand and know the state of the charged device in relation to the amount of electricity already input into the device and to provide with the ability to control it. The switch that is pushed is not to be moved to the extent that the charger is deactivated but not put off. The switch is to be pushed such that it enables the activation of the device and the resultant device functioning.

The light emission by the lamps is an indicator of the operations of the device hence one is able to determine the operation ability and efficiency of the device depending on the emitted lights by the device. The control circuit has to be coupled with the display medium to ensure that the operations of the device are monitored throughout the process without misadministration of the device. With the incorporation of the display system, the user is in a position to determine the whether the device is operating at a rate that is suitable for the transformation of the electricity of the wireless chargeable battery hence the facilitation of the operations of the device.

(Chen, Lin, & Wei, 2006) The use of wireless power transfer will therefore apply the use of magnetic resonance so that it can improve the energy transfer efficency of the device and minimize the losses due to the distances between the coil terminals .this technology therefore will major on the use and application of magnetic resonance of the device such that a wire less charge can be used in the charging of battery of a poratble electronic device.This device will have a side load power transfer coil and the main wireless recharge system.

(Katsuel, Yokohama, Takku, & Fujisawa, 2006) The loop having a single turn is made up of a conductor that is metallic and has the shape of a curve which is closed either circular or squared and has a design that forms terminals within the curve. The axial loop has a great conduction of heat and the current distribution is assumed generally uniform through the wire circuit due to the uniformity in the resistivity of the material wires used in the making of the wire loops. In the receiving loop which is developed at the developed voltage in the respective terminals which are open ended are always proportional to the magnetic flux of the incident radiation to the loop and there is the assumption of the uniformity of the field in the incident area.

To increase the capacity of the open ended circuit it is always necessary to fill the core of the loop with some permeable materials and mostly it is by the use of ferrite and majorly the cores function is for the increasing of the wave flux. With the increase in the sizes of the electrical loops, the distribution of the currents depart from the uniform distribution that is associated with the small loops and the and the change has significant effect on the performance of the loop.when all the parameters and elements of the structure of the loop are factored in, then there will be the optimization of the voltage that is obtained.

The looping system is generally used for the harmonic time dependence and always this approach and usage find application in most practical based approaches in this application due to the efficiency related to its functionalities.
