Resonance Coupling

<p>In the current era of the industrial revolution 4.0, the need for time, labor, and cost efficiency is a basic requirement for human life, especially regarding electrical energy sources. The supply of commercial electricity is still using electricity cables to deliver electricity to the load. Therefore, one of the ways of sending or transferring electrical power that continues to be developed today is wireless electricity transfer. The wireless transfer of electric power has several advantages compared to the use of cables, which can increase the convenience in the use of electrical equipment and can reduce the amount of electronic waste. This research will study the techniques or methods of near-field wireless energy transfer systems, namely the inductive coupling method, the magnetic resonance coupling method and the capacitive coupling method. The results of this study propose an optimal modeling of wireless power transfer so that results and quality are better, taking into account the distance between the sender and receiver because the work efficiency of wireless power transfer decreases with respect to distance. And the signal transmission frequency is low for inductive coupling, while the resulting frequency will be high on magnetic resonance coupling and capacitive coupling.</p>

Transmission Parameters

Magnetic resonance wireless power transmission technology is based on the phenomenon of resonant coupling to realize non-contact power transmission via near magnetic field. Based on the mutual coupling model of resonance system, the influence laws of system transmission parameters, such as coil coupling coefficients, load resistance, etc., on the transmission performance are theoretically studied in this paper. The research results shows that the power high-efficiency and high-quality transmission does not depend on the large coil loop coupling coefficient and the working frequencies of maximum power and maximum efficiency transmission do not coincide at most condition. Transmission systems with a high resonance frequency can produce high power and efficiency transmission over short distances. In addition, by increasing the coil diameter or wire diameter can improve the system quality factor, and optimize the energy transmission performance.
