Abstract :
Electrical energy is one of the basic needs that is very important in human life
today. The delivery of 220 volt low voltage commercial electrical energy still uses
electrical cables. One of the ways of sending or transferring electrical power that
continues to be developed until now is wireless electricity transfer. Transferring
electrical power wirelessly has advantages over using a cable that can increase
comfort in using electrical equipment. In this study a wireless power transfer
system with magnetic induction was developed. With the working principle of the
PLN source connected to the power supply then connected to the transistor and
connected to the primary coil then transmitted to the secondary coil, an
experiment is carried out by changing the number of turns of the wire and the
diameter of the wire which aims to find the maximum power with the number of
turns of the copper wire that has been formed as a primary coil for transmitting
and secondary coil for the recipient to be distributed to the load. Test results on
the Rangkaiaan copper wire with a diameter of 0.6 mm with a number of 33 turns
that can be transferred at a distance of 3 cm with the experimental results can turn
on the 1.3 Watt LED lamp.
