Abstract
The electromagnetic shielding simulation model for space near-field wireless energy transmission system is established in the paper.The influence of transmission power, working voltage, transmission gap length and working frequency on electromagnetic shielding is analyzed, and the effects on coil efficiency and system efficiency, power change and shielding effectiveness are investigated under shielding conditions.In the electromagnetic shielding condition, the simulation results show that when the transmission distance is long, the influence of the shield on the system efficiency increases gradually, the input voltage has little effect on the shielding performance, the load resistance has little effect on system efficiency under shielding condition, and the output power of the system will decrease with the increase of load resistance, the system efficiency and shielding performance decrease slightly with the increase of working frequency.The simulation system can solve the problem of accurate analysis of parameters and shielding effect of near-field wireless energy transmission system for space application in alternating electromagnetic field environment, and the simulation results provide the basis for the design of the system parameters after the electromagnetic shielding of the near-field wireless energy transmission system.关键词
