【Abstract】 Magnetic coupling resonance wireless energy transmission technology is a kind of the technology frontier that has been proposed in recent years, it is suitable for power wireless transmission in medium distance. In this paper, transmission mechanism based on the two air core coil of loose coupling mutual inductance model, the transmission efficiency expression of PSSS system was obtained from the circuit analysis. Through the MathCAD calculation software, the relationship among system transmission efficiency, frequency, secondary load and coupling coefficient was researched. Then through the design air core coils, with SP1651 power signal generator as power supply to verify the transmission efficiency theory, and the experimental results demonstrate the theory. Finally, PSSS of wireless energy transmission device based on L6599 half bridge inverter was design. The device resonance frequency 93.79 kHz, transmission power 15 w, transmission efficiency 87.1%.更多还原
