【摘要】：为探索新型便利的电力传输技术,该文结合之前提出的空间电场耦合单线电力传输(single-wire power transmission,SWPT)系统及其集总参数电路模型,开展了多种基于电路结构和参数的仿真研究。包括输入输出阻抗、输出电压、输出功率,以及传输效率的频率特性;特斯拉变压器高压线圈上端导体对地电容、传输距离、负载阻抗等参数对SWPT系统性能的影响。在仿真过程中,对SWPT系统的电磁现象和规律进行了解释,讨论了两个不同谐振频率的特点,分析了影响传输功率和传输效率的关键因素。最后构建了单线电力传输示范系统,并在室内和室外环境下进行试验,传输距离分别为10和30m,最大传输功率达到80W。单线电力传输的研究可视为实现长无线电力传输的关键步骤之一。
[Abstract]:In order to explore a new and convenient power transmission technology, this paper presents a novel single-wire power transmission SWPTT system and its lumped parameter circuit model. A variety of simulation studies based on circuit structure and parameters are carried out in this paper. It includes the frequency characteristics of input and output impedance, output voltage, output power and transmission efficiency, and the influence of the parameters such as conductors to ground capacitance, transmission distance and load impedance on the performance of SWPT system. In the process of simulation, the electromagnetic phenomena and laws of SWPT system are explained, the characteristics of two different resonant frequencies are discussed, and the key factors affecting transmission power and transmission efficiency are analyzed. Finally, a single-line power transmission demonstration system is constructed and tested in indoor and outdoor environments. The transmission distance is 10 and 30 m.The maximum transmission power is 80 W. The study of single-wire power transmission can be regarded as one of the key steps to realize long-term wireless power transmission.
