Abstract
A prototype of a wireless charging system was designed to tackle the problem of desks being messy as a result of electric cables that are used in charging mobile equipment and the inability to use the mobile devices when they are being charged. The design employs a method which is referred to as strongly coupled magnetic resonance which employs four coils to operate: two self-resonant and two inductors. The system was successfully designed in which power was successfully transmitted between the transmitter and receiver, and a range of about 6cm was achieved. Line of sight was not necessary for the transmission. The output was, however, a low voltage that could power an LED. Further work is required to be carried out to reduce the size of the system and incorporates it in charging mobile equipment.
