IOSR journal of VLSI and signal processing (IOSR-JVSP)Summary: The process of wireless electrical power transfer has been around for quite some time. Its application in
charging of devices wirelessly is ever increasing, especially in charging of portable devices and standalone
batteries. It is a flexible and inexpensive way of power transmission. In this paper, we report that a method
ofwireless electrical power transmission has been designed and developed. Resonance coupling was adopted to
increase the coupling between the transmitter and receiver. This increased the distance of power transmitted
between the receiver and transmitter while also giving the receiver some degree of freedom of orientation,
considering the size of the receiver’s coil. A class D method of power amplification was used because of its high
efficiency to reduce the power lost as heat. While distance of the receiver from the transmitter was not
improved, miniaturization of the system in such a manner suitable for portable devices charging and powering
was achieved. The transmitted voltage can be used to charge a phone, turn on a lamp etc.
