【摘要】：无线电能传输是一种方便、安全的电能传输方式。以实现蓄电池快速无线充电的串联-串联(SS)型谐振无线电能传输系统为研究对象,设计蓄电池三段式充电曲线,提出一种与之相对应的分段跳频控制策略。根据蓄电池充电曲线特征、SS谐振网络的恒压恒流特性和分段跳频控制策略,提出一种适用于蓄电池全范围充电的谐振网络参数优化设计的方法,为无线电能传输系统参数的优化设计提供了理论依据。搭建SS谐振无线电能传输装置,验证了参数选择的合理性和控制策略的有效性。在一次、二次侧之间距离12.5cm下,该装置实现了蓄电池的全范围三段式充电,并且整机效率最优达到93.5%。
[Abstract]:Radio energy transmission is a convenient and safe mode of electric energy transmission. The research object is the series series series SS-based resonant radio energy transmission system which can realize the rapid wireless charging of batteries. The three-stage charging curve of battery is designed, and a corresponding control strategy of frequency hopping is proposed. According to the characteristics of charging curve of battery, the constant voltage and constant current characteristics of SS resonant network and the control strategy of frequency hopping are proposed. This paper presents a method of optimal design of resonant network parameters suitable for the full range charging of batteries, which provides a theoretical basis for the optimization design of radio energy transmission system parameters. The SS resonant radio energy transmission device is built. The rationality of the parameter selection and the effectiveness of the control strategy are verified. At the distance of 12.5cm between the primary and secondary sides, the device realizes the full range three-stage charging of the battery. And the optimal efficiency of the whole machine reached 93.5.
