中文摘要:

相比于传统的有线充电,无线充电是一种更加方便和可靠的充电方式,在电动汽车、生物医学等领域具有较为广泛的应用前景。然而传输效率的低下却限制了无线电能传输技术的进一步推广。磁耦合谐振式做为一种最主要的无线电能传输技术,其主要由高频电源,补偿结构,磁耦合结构以及整流滤波四部分构成。目前磁耦合谐振式无线电能传输系统的传输效率分析时大多仅考虑磁耦合结构的损耗,对系统中高频电源以及整流滤波的损耗考虑欠少。文章在预定效率以及恒功率条件下计算磁耦合谐振式无线电能传输系统中各部分损耗与互感之间的关系,寻求满足系统要求的互感值。最后设计了一套传输功率为1000W,传输效率为85%的磁耦合谐振式无线电能传输系统,实验结果表明文中的损耗计算方法具有较高的准确性。本文研究结果为无线充电系统分析及性能改善起到积极推动作用。

英文摘要:

Compared with traditional wired charging, wireless charging is a more convenient and reliable charging method, which has a wide application prospect in some fields such as electric vehicles and bio-medicine. However, the low transmission efficiency limits the further popularization of wireless energy transmission technology. As one of the most important wireless energy transmission technologies, magnetic-coupled resonance is mainly composed of high-frequency power supply, compensation structure, magnetic coupling structure and rectifier-filter structure. At present, when analyzing the transmission efficiency of magnetic coupling resonant wireless energy transfer system, only the loss of magnetic-coupled structure is considered, but the loss of high-frequency power source and rectifier- filter structure in the system is less considered. In this paper, the relationship between losses and mutual inductance of each part of the magnetic coupling resonant wireless energy transfer system is calculated under the predetermined efficiency and constant power conditions, and the mutual inductance value satisfying the system requirements is sought. Finally, a magnetic coupling resonant wireless energy transfer system with transmission power of 1000W and transmission efficiency of 85% is designed and experimental results show that the loss calculation method is accurate. The research results of this paper play a positive role in promoting the analysis and performance improvement of wireless charging system.
