Study of Load Characteristics and Design for Coil' s Parameters in Magnetically-coupled Resonant Wireless Power Transmission System
摘要
Abstract
Serious influences on transmission properties will be exerted by the variations of systemic electrical parameters in magnetically-coupled resonant wireless power transmission (MCR-WPT) technology.So the investigation of relationships between them shows a material meaning in enhancing the transmission properties.The coil whose design is restricted by lots of factors is one of MCR-WPT system core components.How to capture the parameters which can achieve high efficiency and enough power has perplexed researchers for a long time.To this end,load property is emphasized to study through the equivalent circuit theory.Then the conclusion that the optimal load resistances which make output power and transmission efficiency maximal simultaneously is not subsistent is extracted.The validity of theory analysis is verified through MATLAB.Influence regulations of systemic transmission properties coming from coil' s average radium and number of turns are investigated by MATLAB simulation.The results show that the output power first increases and then decreases as the turns increase when the system works in normal load.Based on the former work,a design for 60 Watt bulb is presented as an example.The designed system can achieve the efficiency of 94 percent when the distance is 0.5 m.Calculation results verify the practicability and reasonability of the coil' s parameters.关键词
