Makalah ini menyajikan hasil perancangan, pengujian dan analisis unjuk kerja prototip sistem pengiriman daya nirkabel menggunakan inverter setengah jembatan dengan teknik resonansi magnetik frekuensi 100 kHz. Pengiriman daya menggunakan rangkaian resonansi magnetik bekerja memindahkan energi listrik dari rangkaian pengirim ke rangkaian penerima melalui resonator yang beroperasi pada frekuensi resonansi. Pada penelitian ini bagian pengirim dan penerima menggunakan kumparan kawat tembaga berdiameter 1,2 mm berbentuk kumparan helix dengan diameter kumparan 10 cm. Catu daya pengirim menggunakan sumber DC 12 V dan dihubungkan dengan inverter setengah jembatan. Sisi penerima dihubungkan dengan rangkaian penyearah diode yang dilengkapi dengan filter untuk mendapatkan tegangan DC. Rangkaian inverter dibuat menggunakan saklar semikonduktor daya MOSFET. Berdasarkan hasil pengujian prototip di laboratorium diperoleh bahwa efisiensi pengiriman daya berkurang terhadap jarak. Semakin jauh jarak antara kumparan pengirim terhadap kumparan penerima, maka efisiensinya menurun. Frekuensi sinyal yang dikirim relatif tetap meskipun jarak kumparan pengirim terhadap kumparan penerima berubah. Sudut antara kumparan penerima terhadap kumparan pengirim yang memberikan efisiensi terbaik adalah 00. Selain itu, untuk hasil pengujian ketika terdapat media yang bersifat isolator di antara kumparan pengirim dan penerima maka transfer daya tidak terganggu. Tetapi ketika terdapat media konduktor maka daya akan terserap oleh konduktor tersebut sehingga efisiensi semakin kecil.

“…Diagram pengiriman daya tanpa kabel ditunjukkan pada Gambar-1. Bagian pengirim berfungsi membangkitkan medan magnet sedangkan bagian penerima berfungsi menerima medan magnet yang ditransmisikan pengirim [5]. Fungsi dari penggunaan inverter adalah agar tegangan dan frekuensi sinyal dapat diatur sebelum sinyal ditransmisikan.…”

“…The researches on wireless electric power transmission were to be encouraged, because of economic considerations compared to cables. Some methods of transmission system power were inductive coupling, inductive coupling resonance, capacitive coupling, magneto dynamic coupling and radioactive techniques [12][13][14][15][16][17][18][19][20].…”

The research was to transfer the electric power from a photovoltaic module in wireless utilized magnetic coupling method and an inverter. It was also investigated the waveform characteristics due to various distances, turns and loads. The measurements were performed by using a storage digital oscilloscope, to obtain the voltage magnitudes and harmonics. The results indicated that the receiver voltage magnitudes would decrease drastically, in hyperbolic curves, as the distance 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 distance 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% in 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 average reduction of 5.4% from one to five lamp loads, for the three turn conditions. The receiver voltage magnitudes would increase steep linearly, with the average ratio of one per 9.30 as the transmitter voltage magnitudes increased. While, 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. The receiver power would reduce more drastically, compared to the voltages, as the distance increased. This case was caused which the powers were influenced by both electric voltage and current. The efficiency would also reduce drastically as the distance increased. Nevertheless, it was gentler than the power, because the early values have already been low. Both parameters were significantly influenced by the coil turns, which the efficiency would be lower as the coil turns reduced. Based on the research results, the maximum transferring efficiency was 0.0615. The efficiency would slightly increase and tended to be saturated toward a certain value as the load increased. Therefore, most likely, in the future, the coil turns should be increased.

“…Similarly, Hertz identified also this transferred power as electrostatic inductions or electrified shock waves that resemble true electromagnetic waves [8]. Finally, Tesla described the travelled charges as light-like rays but he supposed its nature is different from the electromagnetic waves of Maxwell [9].…”

Following an entropy approach, the electric current can be postulated as a flow of electromagnetic waves that has an electric potential. Such postulate is verified in this article by results of experimental measurement then it is applied to review Tesla's discovery of wireless power transmission. Tesla discovered the wireless transmission of electric power during his operation in an entirely new domain of physics based on abrupt discharging of electrostatic charges. He realized that electrons were not responsible for such discovered phenomena. So, he called the new energy as "Radiant Electricity". He didn't identify that the true nature of electric current was a flow of electromagnetic waves that can be normally radiated through air. So, he proposed the term "Aether gas" to describe the discovered transfer of the electric charges by radiation from his designed tower, though air, to specified receivers. Following an entropy approach, the nature of the discovered radiated energy can be identified as electromagnetic waves that have an electric potential. So, the followed approach succeeds in eliminating the confusing observations of Tesla's measurements in his famous experiment and the confusions found in modern literature that deals with such energy as an "Ambiguous Radiant Energy".
