摘要：

Wireless power transmission system via magnetic resonant coupling in the actual design displays its superiority in its higher efficiency, simpler structure, stronger practicability, etc. Research was conducted on the transmission efficiency of the single launch-receive model in series-series model, series-parallel model, parallel-series model and parallel-parallel model under four kinds of resonant model system, from the view of equivalent circuits. By numerical the effects that the operation frequency, distance between the coils and load resistance may have on the efficiency and the output power was obtained. The results show that each resonator model works well under certain conditions, and summarizes the way to choose the corresponding resonant model to achieve the best transmission effect according to the specific situation in the actual design. When the design of the system power supplies for a small load and distance, using the series-series model better result is achieved, and when the design needs to have a longer distance for transmission and strong load capacity, it should be used in series-parallel model. © 2016, Harbin University of Science and Technology Publication.
