Influence of Frequency Characteristics of Resonant Circuits and Power Source on the Efficiency of Inductive Wireless Energy Transfer

摘要

Results of experimental studies of wireless energy transfer are described. The influence of the operating frequency on energy transfer efficiency was studied. The influence of the parameters of the transmitting and receiving resonant circuits of a wireless energy transfer on the output characteristics was investigated.Development of implantable medical devices depends greatly on development and application of technology of percutaneous wireless energy transfer [1-3]. The most promising technique is to use inductive coupling [4-7]. The main advantages of inductive coupling over other solutions (ultrasound or infrared radiation) are the small biological effect of radio waves, relatively low absorption of radio waves by organic media, and relative simplicity of the technical implementation.
