Research on Characteristics of Frequency Splitting in Electromagnetic Coupling Resonant Power Transmission Systems
摘要
Abstract
Resonant state is required both on transmitting and receiving terminal in an electromagnetic field resonance coupling system. However, there may be more than one resonant point when compensation capacitors are introduced. The active power on the load is decreased; furthermore system performance is dropped significantly if control strategy is selected inappropriately. Firstly, a higher order mathematical model of electromagnetic （EM） resonance coupling system was built. Then it discussed the influence of mode coupling factor and quality factor on angular frequency to obtain the change law under different operating conditions. In the experimental aspect, a resonance coupling system contains disc oscillators was designed. It is shown by measurement results that property of frequency splitting is basically consistent with functions derived in the article, so it can be provided as a reference for design an EM resonance coupling system.关键词
