Description
Access to power is a fundamental requirement
for the effective functioning of any electrical/electronic circuit.
The conduit of transfer of power can be either physical (wires,
cables etc.) of non-physical (i.e. wireless). Wireless power
transfer is a broad term used to describe any means used to
transmit power to electricity dependent systems and devices. In
this paper, a wireless power transfer system is developed to
provide an alternative to using power cords for
electrical/electronic devices. With this technology, challenges
like damaged or tangled power cords, sparking hazards and
the extensive use of plastic and copper used in cord production
are resolved and also the need for batteries in non-mobile
devices is eliminated. In this system, electromagnetic energy is
transmitted from a power source (transmitter) to an electrical
load (receiver) via resonant inductive coupling. The
performance achieved is a good indication that power can still
be transmitted over a medium range. In addition, possible
ways of improving the efficiency of the system are discussed.
