RANCANG BANGUN TRANSFER ENERGI LISTRIK TANPA KABEL (WIRELESS TRANSFER ENERGY) BERBASIS TEKNIK RESONANSI INDUKTIF MEDAN ELEKTROMAGNETIK DENGAN BEBAN LISTRIK DC (LED ARRAY 5 WATT)

Currently, electricity is the main necessity of human being, but then issues arise in order to fulfill the electrical energy as the amount of cables used to transfer electrical energy from the source to the loads. Another downside is that less neat cables installation and power losses. Transfer of electrical energy wirelessly has several advantages that it can minimize some of the problems in the use of the cables. The method used to transmit electrical energy without wires in this final project is resonance-inductive electromagnetic field. There are two pieces of copper coils used to generate the inductive resonance together. Wireless power transfer consists of two main circuits. One as an transmitter circuit and another as an receiver circuit. The transmitter circuit consists of step-down transformer, rectifier, amplifier, and transmitter coil. Receiver circuit consists of a receiver coil and rectifier to activate the DC load 5 Watt LED ARRAY. Realization device sends the voltage is in a range between 9.5 VDC - 2.6 VDC, the current that is sent is in a range between 84.8 mA - 0.1 mA and power in the range between 84,8mA - 0.1 mA for distance 0 cm - 30 cm. The farther the distance between the coils, the smaller the electrical energy (voltage, current, and power) is transferred
