Analysis of Wireless Energy Transmission Characteristics via Magnetic Resonances Based on Mutual Inductance Model

Abstract:

The analysis of magnetic coupling resonance based on Mode Coupling theory is often complicated and abstract. Moreover, this theory is inconvenient when it comes to designing the circuits. Based on the mutual inductance in the circuit, we completed theoretical derivation, parameters calculation and circuit simulation for each of the two-coil and the four-coil structure. The received power and the transmission efficiency under different conditions are analyzed and compared. Experimental results show that too high or too low resonant frequency will affect the efficiency of transmission and reception of energy in the two-coil structure, a problem of optimal distance for energy transmission is existed in four-coil structure, the resonant frequency of the system will also affect the distance.
