小功率无线能量传输系统电容补偿方案研究

Study of Compensation Scheme of Small Power Wireless Energy Transporting System

针对电磁感应式无线能量传输系统初级和次级补偿问题,列出了四种补偿方案,推导了补偿电容的选择过程,通过系统仿真,对四种补偿方案的补偿效果进行了分析与比较。结果表明:初级并联-次级并联补偿在低电感情况下补偿效果较好,初级串联-次级串联补偿和初级串联-次级并联补偿在高电感的情况下补偿效果较好。

To study the problem of primary and secondary compensation of small power wireless energy transporting system, four compensation schemes are put forward. The process of choosing compensating capacitance is deduced, and the effects of those compensation schemes are compared by simulations. The result shows that PP model have a good effect in low inductance situation, and the SS model and SP model have a good effect in high inductance situation.
