Abstract

Solar energy is one of renewable and environmentally clean energy, which is very potential to meet electricity demand. Besides that, it is also necessary for wireless power transmission. The purpose of research was to transfer the electric energy in wireless using magnetic couplings and an inverter. It was also investigated the waveform characteristics due to various distances, turns and loads. The tests and measurements were performed by using a storage digital oscilloscope, as the main tool, to obtain the voltage magnitudes and harmonics. The results indicated that the receiver voltage magnitudes would decrease drastically, in hyperbolic curves, as the distances increased. The receiver voltage magnitudes would also decrease considerably as the turns reduced, with the average reductions as 0.095 and 0.357 volts, from 600 to 400 and 400 to 200 turn reductions respectively. The THDs in the transmitter voltages were fairly constant, as average of 26.75%. Nevertheless, the receiver voltage THDs would decrease significantly as the distances increased, with decreasing average as 38.09% of the three condition percentage reductions. While, the THDs would reduce considerably as the turns decreased, as 25.28% of percent average for the 200 to 400 and 400 to 600 turns on one cm of distance. Otherwise, the voltage magnitudes would decrease as the loads increased where from one to five lamp loads, as 0.489, 1.334 and 1.482 volts reductions for 200, 400 and 600 turns respectively. The THDs would decrease slightly as the loads increased, with the reducing average of 5.4% from one to five lamp loads, for the three conditions of turns. The receiver voltage magnitudes would increase steep linearly, with the average ratio of one per 9.30 as the transmitter voltage magnitudes increased. Nevertheless, the THDs of receiver voltages would reduce considerably as the transmitter voltage magnitudes increased, with 8.98% reduction for 1.4 to 5.2 volts of the transmitter voltage magnitudes.
