For the research of wireless power transfer, loosely coupled inductive power transfer (LCIPT) is one of the widely adopted technologies. There are already various researches focusing on development of high-efficiency LCIPT. However, when the transmission and receiver coils are misaligned, the power transfer efficiency will be significantly dropped. This article considers the change of mutual inductance when two induction coils are misaligned. A fuzzy control approach to solve for this problem by adaptively adjusting operational frequency is introduced. Experiments show that it can reduce the power transferring efficiency drop by 11% when two conduction coils are misaligned up to 50 mm. This research also supports adaptive maximum power transfer using tracking mechanism. Before conducting power transmission, the system can choose G2V or V2G according to the vehicle battery capacity via handshaking communication without the need of radio frequency links. In addition, the phase shift pulsewidth modulation technique is proposed for simultaneous data transmission enabling binary quadrature amplitude modulation for digital signal transmission. Fast over current protection is incorporated for power transfer safety when current overload happens. The transmission frequency of this article is controlled to meet the frequency specified by SAE TIR J2954

自适应双向感应功率和数据传输系统
对于无线功率传输的研究,松耦合感应功率传输(LCIPT)是被广泛采用的技术之一。已经有许多研究集中在高效LCIPT的开发上。但是,当发射线圈和接收线圈未对准时,功率传输效率将大大降低。本文考虑了两个感应线圈未对准时互感的变化。介绍了一种通过自适应调整运行频率来解决该问题的模糊控制方法。实验表明,当两个导电线圈未对准50 mm时,它可以将功率传输效率降低11%。该研究还支持使用跟踪机制的自适应最大功率传输。在进行动力传输之前,系统可以通过握手通信根据车辆电池容量选择G2V或V2G,而无需射频链接。另外,提出了用于同时数据传输的相移脉宽调制技术,其使得数字信号传输能够进行二进制正交幅度调制。当发生电流过载时,内置快速过流保护以确保功率传输安全。将本文的传输频率控制为满足以下规定的频率 当发生电流过载时,内置快速过流保护以确保功率传输安全。将本文的传输频率控制为满足以下规定的频率 当发生电流过载时,内置快速过流保护以确保功率传输安全。将本文的传输频率控制为满足以下规定的频率SAE TIR J2954
